A benign pituitary-region neoplasm that originates from Rathke's pouch. The two major histologic and clinical subtypes are adamantinous (or classical) craniopharyngioma and papillary craniopharyngioma. The adamantinous form presents in children and adolescents as an expanding cystic lesion in the pituitary region. The cystic cavity is filled with a black viscous substance and histologically the tumor is composed of adamantinomatous epithelium and areas of calcification and necrosis. Papillary craniopharyngiomas occur in adults, and histologically feature a squamous epithelium with papillations. (From Joynt, Clinical Neurology, 1998, Ch14, p50)
Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
Benign and malignant tumors of the HYPOTHALAMUS. Pilocytic astrocytomas and hamartomas are relatively frequent histologic types. Neoplasms of the hypothalamus frequently originate from adjacent structures, including the OPTIC CHIASM, optic nerve (see OPTIC NERVE NEOPLASMS), and pituitary gland (see PITUITARY NEOPLASMS). Relatively frequent clinical manifestations include visual loss, developmental delay, macrocephaly, and precocious puberty.

Diminution or cessation of secretion of one or more hormones from the anterior pituitary gland (including LH; FOLLICLE STIMULATING HORMONE; SOMATOTROPIN; and CORTICOTROPIN). This may result from surgical or radiation ablation, non-secretory PITUITARY NEOPLASMS, metastatic tumors, infarction, PITUITARY APOPLEXY, infiltrative or granulomatous processes, and other conditions.
A tumor composed of cells resembling those of the hair matrix, which undergo 'mummification' and may calcify. It is a relatively uncommon tumor, which may occur at any age from infancy. The majority of patients are under 20, and females are affected more than males. The lesion is usually a solitary deep dermal or subcutaneous tumor 3-30 mm in diameter, situated in the head, neck, or upper extremity. (From Rook et al., Textbook of Dermatology, 4th ed, p2401)
Ocular disorders attendant upon non-ocular disease or injury.
A disease that is characterized by frequent urination, excretion of large amounts of dilute URINE, and excessive THIRST. Etiologies of diabetes insipidus include deficiency of antidiuretic hormone (also known as ADH or VASOPRESSIN) secreted by the NEUROHYPOPHYSIS, impaired KIDNEY response to ADH, and impaired hypothalamic regulation of thirst.
Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.
Congenital or acquired cysts of the brain, spinal cord, or meninges which may remain stable in size or undergo progressive enlargement.
A narrow cleft inferior to the CORPUS CALLOSUM, within the DIENCEPHALON, between the paired thalami. Its floor is formed by the HYPOTHALAMUS, its anterior wall by the lamina terminalis, and its roof by EPENDYMA. It communicates with the FOURTH VENTRICLE by the CEREBRAL AQUEDUCT, and with the LATERAL VENTRICLES by the interventricular foramina.
A mixed radiolucent-radiopaque lesion of the jaws with features of both a cyst and a solid neoplasm. It is characterized microscopically by an epithelial lining showing a palisaded layer of columnar basal cells, presence of ghost cell keratinization, dentinoid, and calcification. (Stedman, 25th ed)

Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (SKULL NEOPLASMS).
A genetic or acquired polyuric disorder caused by a deficiency of VASOPRESSINS secreted by the NEUROHYPOPHYSIS. Clinical signs include the excretion of large volumes of dilute URINE; HYPERNATREMIA; THIRST; and polydipsia. Etiologies include HEAD TRAUMA; surgeries and diseases involving the HYPOTHALAMUS and the PITUITARY GLAND. This disorder may also be caused by mutations of genes such as ARVP encoding vasopressin and its corresponding neurophysin (NEUROPHYSINS).
An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).
Pathological processes of the ENDOCRINE GLANDS, and diseases resulting from abnormal level of available HORMONES.
A demyelinating condition affecting the PONS and characterized clinically by an acute progressive QUADRIPLEGIA; DYSARTHRIA; DYSPHAGIA; and alterations of consciousness. Pathologic features include prominent demyelination in the central PONS with sparing of axons and neurons. This condition is usually associated with systemic disorders such as HYPONATREMIA; chronic ALCOHOLISM; LIVER FAILURE; severe BURNS; malignant NEOPLASMS; hemorrhagic PANCREATITIS; HEMODIALYSIS; and SEPSIS. The rapid medical correction of hyponatremia has been cited as a cause of this condition. (From Adams et al., Principles of Neurology, 6th ed, pp1125-6)
Cancers or tumors of the MAXILLA or MANDIBLE unspecified. For neoplasms of the maxilla, MAXILLARY NEOPLASMS is available and of the mandible, MANDIBULAR NEOPLASMS is available.
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.
Special hospitals which provide care for ill children.
A rare but highly lethal childhood tumor found almost exclusively in infants. Histopathologically, it resembles RHABDOMYOSARCOMA but the tumor cells are not of myogenic origin. Although it arises primarily in the kidney, it may be found in other parts of the body. The rhabdoid cytomorphology is believed to be the expression of a very primitive malignant cell. (From Holland et al., Cancer Medicine, 3d ed, p2210)
A diagnostic technique that incorporates the measurement of molecular diffusion (such as water or metabolites) for tissue assessment by MRI. The degree of molecular movement can be measured by changes of apparent diffusion coefficient (ADC) with time, as reflected by tissue microstructure. Diffusion MRI has been used to study BRAIN ISCHEMIA and tumor response to treatment.

Cyclic compression of the intracranial optic nerve: patterns of visual failure and recovery. (1/203)

A patient with a cystic craniopharyngioma below the right optic nerve had several recurrences requiring surgery. Finally the cyst was connected with a subcutaneous reservoir by means of a fine catheter. Symptoms of optic nerve compression recurred more than 50 times during the following year, and were relieved within seconds upon drainage of the reservoir. In each cycle, a drop in visual acuity preceded a measurable change in the visual field. The pattern of field changes was an increasingly severe, uniform depression. Optic nerve ischaemia induced by compression was probably the most important factor causing visual failure in this case.  (+info)

Recovery from anterograde and retrograde amnesia after percutaneous drainage of a cystic craniopharyngioma. (2/203)

A case is reported of a cystic craniopharyngioma involving the floor and walls of the third ventricle. Pronounced anterograde and retrograde amnesia were documented preoperatively by formal testing. Rapid improvement in both new learning capacity and remote memory occurred after percutaneous twist drill drainage of the cystic portion of the tumour. The relevance of these observations to the amnesic syndrome and its neuropathological basis is discussed.  (+info)

CT-guided stereotactic biopsy of deep brain lesions: report of 310 cases. (3/203)

OBJECTIVE: To evaluate the accuracy of CT-guided stereotactic biopsy in making correct pathological diagnosis and choosing corresponding management of brain tumors. METHODS: From 1991 to 1995, CT-guided stereotactic biopsy was performed in 310 patients with intracerebral lesions which were deep-seated or located in certain main functional areas. The patients were 198 men and 112 women. Their ages ranged from 4.5 to 70 years (average: 39.3 years). The lesions were located in the deep cerebrum (74 patients), the sellar area (62), the basal ganglion (51), the posterior part of the third ventricle (38), other intraventricleular area (21), the cerebellum (17) and the brain stem (9), and intracranial multiple lesions were found in 38 patients. RESULTS: Brain tumors were diagnosed pathologically in 266 patients (85.8%); inflammatory process in 25 (8.1%), other lesions in 8 (2.6%) and uncertain cases were 11 (3.6%). The overall positive rate of biopsy was 96.4% and the positive rate for brain tumor was 85.8%. Intracranial hematomas after biopsy were found in 5 patients (1.6%). There were no deaths induced by the biopsy or other serious complications. CONCLUSIONS: The results suggest that CT-guided stereotactic biopsy is a reliable method for histopathological diagnosis of brain tumors and it is also of great help in selecting appropriate management.  (+info)

Suprasellar arachnoid cyst presenting with precocious puberty : report of two cases. (4/203)

Suprasellar arachnoid cysts (SSAC) are uncommon intracranial lesions. Two patients of SSAC presenting with precocious puberty are described. In both the cases partial excision of the cyst wall, through a pterional craniotomy, establishing communication with the basal subarachnoid spaces was carried out. The endocrinological symptoms regressed after surgery. The clinical presentations of SSAC and the treatment options available are reviewed.  (+info)

Metastatic craniopharyngioma. (5/203)

We report a unique case of metastatic craniopharyngioma. Initially, the patient had a right frontal craniotomy for resection of a suprasellar mass, which was determined to be an adamantinomatous craniopharyngioma. Seven years later, an MR study of the brain showed two peripheral enhancing lesions adjacent to the dura and contralateral to the craniotomy site. Pathologic examination again showed adamantinomatous craniopharyngioma. Although recurrence, both local and along surgical tracts due to implantation of craniopharyngioma tissue, has been reported, this case raises the possibility of meningeal seeding to remote sites.  (+info)

Atypical Rathke's cleft cyst associated with ossification. (6/203)

We report a case of symptomatic Rathke's cleft cyst with ossification. CT scans showed curvilinear calcification on the wall of the cyst. MR images revealed a cystic sellar lesion with a nodular solid mass extending to the floor of the third ventricle. This case shows that calcification of the suprasellar cyst does not always suggest craniopharyngioma. Rathke's cysts should be histologically differentiated from craniopharyngiomas because their treatments are different.  (+info)

Long-term magnetic resonance imaging follow-up of asymptomatic sellar tumors. -- their natural history and surgical indications. (7/203)

Serial magnetic resonance (MR) images and clinical symptoms were analyzed in 23 patients with sellar lesions, who were followed up without initial therapy for mass reduction to evaluate their natural history and surgical indication for these lesions. The patients were aged 17 to 78 years (mean 47.3 years) and the follow-up period was 1.5 to 11.6 years (mean 5.1 years). Lesions were divided into two types based on the MR imaging findings, regardless of their histological types. Type C was cystic with or without enhancement of the smooth and thin wall. Type S had enhanced solid components. Ten patients had Type C tumors. Three patients presented with sudden onset of headache. The tumor size spontaneously decreased with intensity change, indicating pituitary apoplexy as the trigger of the onset and intensity change. Four patients presented with the visual disturbance which improved with the reduction of tumor size, but three patients deteriorated and required surgery. The operation revealed Rathke's cleft cyst. The remaining three patients were found incidentally and have been asymptomatic without MR imaging changes. Thirteen patients had Type S tumors. Six patients of nine with 14 mm or larger tumors developed symptomatic tumor enlargement over the follow-up period of 1.2 to 8.6 years (mean 4.9 years) and required treatment. The remainder showed no change. Type C tumors frequently shrink or even disappear spontaneously. We can justify conservative follow-up of Type C tumors in patients with no or only transient symptoms. Type S tumors, larger than 14 mm in size, need closer observation or treatment because they often enlarge and become symptomatic.  (+info)

Tension pneumocephalus after neurosurgery in the supine position. (8/203)

Tension pneumocephalus has been reported most frequently after posterior fossa surgery performed in the sitting position. We present a paediatric patient who developed tension pneumocephalus in the postoperative period after decompression of a craniopharyngioma performed with the patient in the supine position.  (+info)

Craniopharyngiomas are benign tumours that show a bimodal age distribution and arise in two distinct clinicopathological variants: the adamantinomatous and the papillary subtypes.1 The molecular mechanisms involved in craniopharyngiomas remain elusive. While a genetic susceptibility is not known, there are reports describing the occurrence of craniopharyngiomas in consanguineous siblings2 as well as in a mother and daughter.3 To date, cytogenetic (that is, karyotypic) data on only 11 craniopharyngiomas have been published,5-,8 and have shown multiple chromosomal abnormalities in two cases, both of which involved chromosomes 2 and 12,5,7 while the other nine cases presented with normal karyotypes6,8; four additional craniopharyngiomas showed no mutations of the TP53 tumour suppressor gene.9 In view of the association of naevoid basal cell carcinoma or Gorlin syndrome with the occurrence of craniopharyngiomas, a recent study was carried out on 22 adamantinomatous craniopharyngiomas. This found no ...

Craniopharyngiomas (CP) are rare epithelial tumors of the sellar region. Two subtypes, adamantinomatous (adaCP) and papillary CP (papCP), were previously identified based on histomorphological and epidemiological aspects. Recent data indicates that both variants are defined by specific genetic alterations, and influenced by distinct molecular pathways and particular origins. The fact that CP is an uncommon tumor entity renders studies on large cohorts difficult and exceptional. In order to achieve further insights distinguishing CP variants, we conducted whole genome methylation (450 k array) and microarray-based gene expression studies in addition to CTNNB1 and BRAF mutation analysis using a comprehensive cohort of 80 adaCP and 35 papCP. BRAF V600E mutations were solely found in the papCP subgroup and were not detectable in adaCP samples. In contrast, CTNNB1 mutations were exclusively detected in adaCP. The methylome fingerprints assigned DNA

N2 - BACKGROUND: Craniopharyngiomas are slow-growing, locally invasive intracranial tumors that can generate considerable morbidity, and recurrences are often difficult to manage. Because reliable morphologic criteria for accurately predicting the clinical outcome of these tumors are lacking, we evaluated the growth potential of craniopharyngiomas by measuring their proliferative activity based on MIB-1 immunostaining for the Ki-67 antigen, which is expressed during all phases of the cell cycle except G0. METHODS: Paraffin sections from 37 cases of craniopharyngiomas were immunostained with the monoclonal antibody MIB-1, and a labeling index was derived in each case from an the with the ...
AbstractIntroduction: Craniopharyngioma of childhood are commonly cystic in nature. An intracystic catheter insertion and subsequent instillation of substances inducing cyst shrinkage seems a beneficial strategy avoiding additional morbidity in a highly vulnerable brain location. Methods: A systematic review of the medical literature was performed to identify potentially relevant, all languages articles using Ovid MEDLINE and EMBASE from inception to July 2011 and Cochrane Central Register of Controlled Trials to 3rd quarter 2011. All references were examined for relevancy. Results: Of 142 unique references x referred to substances used for intracystic craniopharyngioma treatment. General aspects of intracystic catheter insertion as well as response rates, risks and outcomes of children treated with intracystic radio-isotopes, bleomycin and interferon are critically reviewed and an outline for potential future endeavours provided. Conclusions: Interferon seems currently the intracystic substance with

OBJECTIVE: Suprasellar craniopharyngiomas have been classically removed using a variety of transcranial approaches. Historically, the transsphenoidal route was reserved for intrasellar-infradiaphragmatic, and preferably cystic, lesions. With the advent of the endoscope in transsphenoidal surgery, its obvious advantages combined with neurosurgeons increasing interest in extended transsphenoidal approaches made suprasellar and even intraventricular craniopharyngiomas accessible for removal via such a low route.. PATIENTS AND METHODS: Between January of 2004 and April of 2006, six men and four women (mean age, 57.2 yr; range, 26-70 yr) underwent surgery for craniopharyngioma, including two intrasuprasellar, one suprasellar, six suprasellar-intraventricular, and one that was purely intraventricular. Three patients had undergone a previous transcranial surgery via the pterional approach, whereas one patient had undergone a transsphenoidal microsurgical approach. The surgical method consisted of an ...
Genes involved in formation/development of the adenohypophysis, CTNNB1 gene, and microRNAs might be implicated in the craniopharyngioma pathogenesis. The objective of this study is to perform the molecular analysis of HESX1, PROP1, POU1F1, and CTNNB1 genes and evaluate a panel of miRNA expression in craniopharyngioma. We also verified whether the presence of CTNNB1 mutation is associated with clinical findings and miRNA expression. The study included 16 patients with adamantinomatous craniopharyngioma (nine children and seven adults; eight females and eight males; 6-55 years, median 15.5 years). DNA, RNA, and cDNA were obtained from craniopharyngioma and normal pituitaries. DNA was also extracted from peripheral blood of healthy subjects. All genes were amplified by polymerase chain reaction and direct sequenced. Relative quantification of miRNA expression was calculated using the 2(-ΔΔCt) method. We found no mutations in HESX1, PROP1, and POU1F1 genes and four polymorphisms in PROP1 gene ...
Craniopharyngiomas are most commonly located extraaxially in the suprasellar area. They are benign but aggressive neoplasms. An adult patient is reported to have a huge craniopharyngioma with gross extensions to the surroundings. In diffusion MRI, it had high signal for b=1000 mm(2)/s (true diffusio …
Craniopharyngiomas are benign epithelial tumors of the sellar region but can have significant neurological and endocrinological consequences and may require treatment that will cause further morbidity. The first description of a craniopharyngioma is credited to Zenker, who made this observation in 1857.
Craniopharyngiomas have always been an extremely challenging type of tumor to treat. The transsphenoidal route has been used for resection of these lesions since its introduction. The authors present a historical review of the literature from the introduction of the endonasal route for resection of craniopharyngiomas until the present. Abandoned early due to technological limitations, this approach has been expanded both in its application and in its anatomical boundaries with subsequent progressive improvements in outcomes. This expansion has coincided with advances in visualization devices, imaging guidance techniques, and anatomical understanding. The progression from the use of headlights, to microscopy, to endoscopy and fluoroscopy, and finally to modern intraoperative magnetic resonance-guided techniques, combined with collaboration between otolaryngologists and neurosurgeons, has provided the framework for the development of current techniques for the resection of sellar and suprasellar ...
Craniopharyngiomas (see the image below) are histologically benign neuroepithelial tumors of the CNS that are predominately observed in children aged 5-10 years.{file44804}These tumors arise from squamous cell embryologic rests found along the path of the primitive adenohypophysis and craniopharyngeal duct.
Surgery with cyst drainage. Surgery may be done to drain tumors that are mostly fluid-filled cysts. This lowers pressure in the brain and relieves symptoms. A catheter (thin tube) is inserted into the cyst and a small container is placed under the skin. The fluid drains into the container and is later removed. Sometimes, after the cyst is drained, a drug is put through the catheter into the cyst. This causes the inside wall of the cyst to scar and stops the cyst from making fluid or increases the amount of the time it takes for the fluid to build up again. Surgery to remove the tumor may be done after the cyst is drained.. Chemotherapy. Chemotherapy is a treatment that uses anticancer drugs to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach tumor cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly ...
Since a craniopharyngioma grows near the pituitary gland, symptoms are caused by the pressure the growing tumor puts on that glad as well as on nearby structures. The symptoms depend on what structure is being compressed:

Last updated: 8/5/2016. Cause. The cause of these tumors is not well understood; however, researchers suspect that they begin during the early stages of development in pregnancy (embryogenesis) and may result from metaplasia (abnormal transformation of cells). Craniopharyngiomas are thought to arise from epithelial remnants of the craniopharyngeal duct or Rathkes pouch, which are developmental structures related to gut (stomach) formation. Embryonic cells (early fetal cells) from abnormal development of the craniopharyngeal duct or anterior pituitary gland may give rise to a craniopharyngioma. These tumors are closely related to another cystic mass occasionally seen in the pituitary called Rathkes cleft cyst.[3][4][5]. Last updated: 8/5/2016. Treatment. There are several different types of treatment for craniopharyngiomas which may include a combination of the following: surgery to remove the full or partial tumor (resection), radiation therapy, cyst drainage, chemotherapy, and biologic ...
RADIOLOGY: HEAD: Case# 33611: CRANIOPHARYNGIOMA. This 21 old male presented with inability to see anything off to the side. T1 weighted coronal MRI after gadolinium reveals a cystic mass above the sella with peripheral enhancement. Craniopharyngioma arise from rests of squamous epithelium left following involution of the hypophyseal-Rathkes duct. Most arise in children or young adults, with the peak incidence around ten years of age. In children they account for one half of all suprasellar tumors. On imaging studies they are lobulated cystic masses with mural nodules. Calcification of the rim and/or nodule is seen in most cases. Enhancement of the rim and nodule is also typical. The high signal cyst fluid seen on T1 weighted MR images in some cases is related to high protein content and/or blood breakdown products. Three quarters are entirely suprasellar, with most of the rest being both intra- and suprasellar. Only rarely are craniopharyngioma entirely within the sella.. ...
Charles H. Frazier (1870-1936), one of the pioneers of neurosurgery in the US, is known worldwide for devising surgical procedures to relieve trigeminal neuralgia and intractable pain. Less well-known are his substantial contributions to understanding and treating pituitary and parahypophyseal lesions. Along with Bernard Alpers, he defined Rathkes cleft tumors as a different pathological entity from adenomas and hypophyseal stalk tumors (craniopharyngiomas [CPs]). The surgical challenge posed by CPs piqued Fraziers interest in these lesions, although he never published a complete account of his CP series. An examination of the Charles Frazier papers at the College of Physicians of Philadelphia allowed the authors to identify 54 CPs that he had treated during his career. In the early 1910s, Frazier developed the subfrontal approach, which would become the primary surgical route to access these lesions, providing better control of the adjacent vital neurovascular structures than the ...

We identified 24 previously reported cases in addition to our three cases. Mean age was 36.6 years (range 5-68). There were 16 (59%) females. The most common (74%) presenting symptom was endocrinological deficits, typically either isolated diabetes insipidus (DI) or panhypopituitarism. Location was intrasellar in 3 (11%), suprasellar in 6 (22%), and intrasellar/suprasellar in 18 (67%) patients. Lesions were most commonly (83%) T1 hyperintense. Gross total resection was achieved in 16 (64%) and subtotal resection in 9 (36%) patients. Of the seventeen (63%) patients presenting with varying degrees of bitemporal hemianopsia, all had improvement in vision postoperatively. It is worth noting that no cases of preoperative hypopituitarism or DI improved postoperatively. Even though gross total resection was only achieved in 64%, there was only one recurrence reported. ...

Radiation therapy is commonly used to treat a variety of brain tumors in children including ependymoma, craniopharyngioma and low- and high-grade glioma. The ability of the therapy to control brain tumors in children is known to depend on the tumor type, extent of resection and other clinical factors. Children who received radiation therapy on this study were evaluated for treatment failure at 12 months. In addition to the primary objective, the study was designed to explore the association between radiation dose and volume and a variety of neurological, endocrine and cognitive deficits up to 5 years after treatment ...
Story told by Jenny Shapiro- Mother of Alexis When Alexis was diagnosed with a brain tumor, I had never imagined what this would mean for our family long-term. The type of brain tumor she had is called Craniopharyngioma; which is a rare tumor found near the pituitary gland.. Although the surgery to remove the tumor a few years ago was a success; it in turn damaged Alexiss hypothalamus and pituitary gland, which are two organs that help regulate energy balance, appetite, and weight. My daughters adrenal insufficiency leaves her vulnerable to potentially lethal blackouts.. As we were leaving the hospital after her surgery, the doctor explained to us the extreme importance of carrying an emergency needle and vial of a special steroid called Solu- Cortef, which must be injected within minutes after feeling any symptoms. Without this hormone in her body; my daughter could easily become unresponsive very quickly, or even comatose.. This was profoundly frightening to me as a mother. I reached the ...
h2,How is a craniopharyngioma treated?,/h2,,h3,Surgery when the tumour is mostly solid,/h3,,p,One approach to treatment is to remove as much of the tumour as possible using surgery. This can be difficult because these tumours stick to nearby tissues. ,/p,,p,If only part of the tumour is removed in surgery, then radiation therapy may be used to treat the remaining tumour. Radiation involves the use of high-energy X-rays, gamma rays, or electrons to destroy tumour cells. ,/p,,p,Before the main operation to remove the tumour, the surgeon may need to do a smaller operation. If one of the cysts is pressing against an important part of the brain and causing an increase in pressure, the surgeon may decide to drain the fluid in the cyst. He will make a small hole (burr hole) in the skull and insert a tube into the cyst to drain it or he may put a permanent shunt in called an Ommaya reservoir. ,/p,,h3,Surgery when the tumour is mostly cystic,/h3,,p,If one of the cysts is pressing against an important ...
Shannon was diagnosed with a rare craniopharyngioma brain tumour when she was just nine-years-old. She underwent emergency surgery and has endured several operations over the years, plus treatment including radiotherapy and hormone replacement. Now 18, and a college student, she is certified blind and relies on a long cane to help her get about. She is looking forward to leaving home and studying at university.

Craniopharyngioma is a common tumor in childhood, but can also be seen in adults. These tumors often present with endocrine problems, abnormalities of appetite, visual problems. MRI gives diagnosis and treatment involves surgery. Attempt must be made at complete excision, with safeguarding of vital hypothalamic functions. Radiation may be required after surgery to halt tumor followed by surgical excision, with excellent results.. ...

At the European Molecular Biology Laboratory (EMBL) in Heidelberg, Professor Parton was mentored by Gareth Griffiths, where he honed his skills in electron microscopy while collaborating with other groups throughout the institute including Jean Gruenberg and Marino Zerial. He has maintained these collaborations to this day, despite the groups now being spread around the globe.. Collaboration has been central to his career. In a collaborative project with the laboratory of Kai Simons, he observed that the newly-discovered protein, VIP21 (later renamed caveolin-1), was an abundant marker protein of caveolae. Also at the EMBL Parton and Michael Way discovered a second member of the caveolin family, M-caveolin, now termed caveolin-3.. At The University of Queensland he collaborated with Professor John Hancock. Together they showed that caveolin mutants can act as dominant negative inhibitory mutants and that one of the mutants was a highly potent inhibitor of Ras signalling. Inhibition was specific ...

Methods: Eighteen patients with residual or recurrent craniopharyngiomas underwent radiosurgery with the use of multiple isocenters, mainly of smaller size, which were positioned compactly within the border of the lesion with resultant improved dose homogeneity, increased average dose within the target, and sharp dose fall outside the treated volume. Treatment ...
Thirst is stimulated by increases in effective plasma osmolality that are detected by cerebral osmoreceptors located in the vascular organ of the lamina terminalis. However, surgical destruction or organic lesions of the lamina terminalis decrease the sensation of thirst in response to increased plasma osmolality. A 17-year-old boy who was diagnosed with craniopharyngioma at the age of 10 years and underwent tumor resection and gamma knife surgery was admitted for non-symptomatic severe hypernatremia. Although the sodium level was 173 mmol/L and serum osmolality was also high (371 mOsm/kg), the patient did not report increased thirst. Laboratory analysis revealed hypertonic dehydration and acute non-oliguric renal failure due to dehydration. Treatment was based on correction of hypernatremia with hydration and education about regular, periodic water ingestion. The patients hypernatremia and acute non-oliguric renal failure resolved with controlled daily fluid intake. To our knowledge, this is ...
This patient presented with hyperprolactinemia. MRI reveals T1/T2 hyperintense lesion in the left posterior aspect of the pituitary with convex superior margin with minimal enhancement on post contrast scans. The pituitary stalk is deviated to right. Fluid level is noted in the axial section. The optic chiasm & cavernous sinus appears normal. No parasellar abnormality. Differentials include first differential of rathkes cleft cyst versus other possibility of cystic adenoma. Rathkes cleft cysts are nonneoplastic, sellar or suprasellar epithelium-lined cysts arising from the embryologic remnants of Rathkes pouch in the pituitary gland. Hyperprolactinemia in Rathke cleft cyst is due infundibular stalk compression. ...
A Rathkes cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid-filled cyst in the posterior portion of the anterior pituitary gland. It occurs when the Rathkes pouch does not develop properly and ranges in size from 2 to 40mm in diameter. Asymptomatic cysts are commonly detected during autopsies in 2 to 26 percent of individuals who have died of unrelated causes. Females are twice as likely as males to develop a cyst. If a cyst adds pressure to the optic chiasm, it may cause visual disturbances, pituitary dysfunction, and headaches. The majority of pituitary patients with chronic headaches have Rathkes Cleft Cysts. This is believed to be caused by the constant change in volume and the drastic changes in vasopressure from fluctuations in gonadotrophs and ADH. The treatment of choice for symptomatic cysts is drainage and taking a biopsy. Radical excision is more dangerous because of the potential of damaging the patients pituitary function e.g. ADH ...
In embryogenesis, Rathkes pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system. Rathkes pouch, and therefore the anterior pituitary, is derived from ectoderm. The pouch eventually loses its connection with the pharynx giving rise to the anterior pituitary. The anterior wall of Rathkes pouch proliferates, filling most of the pouch to form pars distalis and pars tuberalis. The posterior wall forms pars intermedia. In some organisms, the proliferating anterior wall does not fully occupy Rathkes pouch, leaving a remnant (Rathkes cleft) between the pars distalis and pars intermedia. Rathkes pouch may develop benign cysts. Craniopharyngioma is a neoplasm which can arise from the epithelium within the cleft. It is named for Martin Rathke. Rathkes cleft cyst synd/3564 at Who Named It? M. H. Rathke. Entwicklungsgeschichte der Natter (Coluber natrix). ...
Ophthalmologists are often the first port of consultation and patients may present with headache, unilateral or bilateral visual loss, visual field loss, hemislide phenomenon, post fixational blindness, see-saw nystagmus, cranial nerve palsy, papilledema, and bow tie optic atrophy. Besides causing the chiasmal syndrome most commonly, craniopharyngioma has infrequently been reported to cause junctional scotoma, paracentral bitemporal hemianopia(anterior or posterior optic chiasma syndrome) or homonymous hemianopia (optic tract syndrome). However because of the suprachiasmatic location of the tumour there is a clear association between inferior visual field defects and craniopharyngioma, but in clinical practice most patients do not present with inferior field loss (as in our patient) (4). Pleomorphism- distinct change from one type of field defect into another type of visual field defect- is characteristic of craniopharyngioma. It is related to intermittent emptying of cyst fluid into ventricular ...
The craniopharyngiomas are solid cystic suprasellar tumors that can present extension to adjacent structures, conditioning pituitary and hypothalamic dysfunction. Within hypothalamic neuroendocrine dysfunction, we can find obesity, behavioral changes, disturbed circadian rhythm and sleep irregularities, imbalances in the regulation of body temperature, thirst, heart rate and/or blood pressure and alterations in dietary intake (like anorexia). We present a rare case of anorexia-cachexia syndrome like a manifestation of neuroendocrine dysfunction in a patient with a papillary craniopharyngioma. Anorexia-cachexia syndrome is a complex metabolic process associated with underlying illness and characterized by loss of muscle with or without loss of fat mass and can occur in a number of diseases like cancer neoplasm, non-cancer neoplasm, chronic disease or immunodeficiency states like HIV/AIDS. The role of cytokines and anorexigenic and orexigenic peptides are important in the etiology. The ...
J Neurosurg 124:627-638, 2016. Craniopharyngiomas and similar midline suprasellar tumors have traditionally been resected via transcranial approaches. More recently, expanded endoscopic endonasal transsphenoidal approaches have gained interest. Surgeons have advocated for both approaches, and at present there is no consensus whether one approach is superior to the other. The authors therefore compared surgical outcomes between craniotomy and endoscopic endonasal transsphenoidal surgery (EETS) for suprasellar tumors treated at their institution.. Methods: A retrospective review of patients undergoing resection of suprasellar lesions at Cedars-Sinai Medical Center between 2000 and 2013 was performed. Patients harboring suspected craniopharyngioma were selected for extensive review. Other pathologies or predominantly intrasellar masses were excluded. Cases were separated into 2 groups, based on the surgical approach taken. One group underwent EETS and the other cohort underwent craniotomy. Patient ...

Objective: The presented single-centre study summarizes the outcome after intracavitary brachytherapy (IBT) using stereotactically applied phosphorus-32 (32P) colloid for the treatment of cystic craniopharyngiomas. We assessed its efficacy and safety, based on tumor control and endocrinological, ophthalmological, and neurological outcomes in one of the largest reported patient series.. Methods: Between April 1992 and January 2011, 53 patients (including 19 children aged , 20 y) with 56 cysts were treated with IBT-14 had no prior treatment and 39 had been treated for recurrent cysts. The intervention was performed by applying 200 Gy (median, range: 200-250 Gy) to the internal cyst wall (median volume 6.1 ml). The median clinical and radiological follow-up was 60.2 and 53.0 months, respectively.. Results: The actuarial tumor cyst control rate was 86.0 5.3% at 12, 24, and 60 months. The development of new cysts or progression of solid tumor parts (out-of-field progression) occurred in 18 patients ...

Cystic sellar lesions are a rare cause of hypopituitarism and extremely rare in the pediatric age group. The differential diagnosis is large and includes both primary pituitary abscesses and cystic components on pre-existing lesions, such as adenoma, craniopharyngioma, Rathkes cleft cyst, leukemia, granulomatous disease and lymphocytic hypophysitis. In the absence of a definitive diagnosis, treatment can be challenging. We report a case of a 15-year-old female, who presented with headaches, altered consciousness and diplopia after a molar extraction, for which she had received oral antibiotics. Broad-spectrum i.v. antibiotics were given for presumed meningitis. Blood cultures failed to identify pathogens. Cerebral magnetic resonance imaging showed a pituitary cystic lesion. Endocrine studies revealed abnormal pituitary function. In the absence of a therapeutic response, the patient underwent a transsphenoidal biopsy of the pituitary gland, which yielded a purulent liquid, but cultures were ...
Appearances are unaltered. A cystic lesion mostly fills the pituitary fossa and bulges into the suprasellar cistern and not compressing or distorting the optic chiasm. It measures 17 x 10 by 11 mm, unaltered when compared to previous imaging, it continues to have a T1 hyper intensity and T2 hypointense (previous imaging) nodule posteroinferiorly within the cyst, which does not enhance. The remainder of the imaged brain (please note this study has been targeted to the pituitary, and as such the whole brain has not been imaged) appears unremarkable.. Conclusion:. Stable appearances when compared to previous imaging, and remain most consistent with a Rathkes cleft cyst. Particularly the luminal nodule, although unusually large, is quite characteristic. ...
Adipsia combined with diabetes insipidus after hypothalamic damage may produce major difficulties in clinical management. If there is an associated memory impairment it may be impossible to teach self-regulation of fluid balance, necessitating long-term hospital supervision. The successful use of a behaviour modification technique to achieve independent drinking and allow discharge from hospital into the community is described in a patient with adipsia, diabetes insipidus and memory impairment resulting from the removal of a craniopharyngioma.. ...
In Females: HMG is used in a sequential manner in conjunction with HCG for the induction of ovulation and pregnancy in the anovulatory infertile patient in whom the cause of anovulation is functional (secondary to pituitary insufficiency) and is not due to primary ovarian failure. HMG and HCG may also be used to stimulate the development of multiple follicles in ovulatory patients participating in an in-vitro fertilization program. In Males: HMG is used in conjunction with HCG to stimulate spermatogenesis in primary hypogonadotropic hypogonadism (resulting from hypophysectomy, craniopharyngioma, cerebral aneurysm or chromophobe adenoma ...
