Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
Radiographic visualization of the cerebral ventricles by injection of air or other gas.
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.

Trans-sphenoidal surgery for microprolactinoma: an acceptable alternative to dopamine agonists? (1/182)

AIMS: Reported cure rates following trans-sphenoidal surgery for microprolactinoma are variable and recurrence rates in some series are high. We wished to examine the cure rate of trans-sphenoidal surgery for microprolactinoma, and to assess the long-term complications and recurrence rate. DESIGN: A retrospective review of the outcome of trans-sphenoidal surgery for microprolactinoma, performed by a single neurosurgeon at a tertiary referral centre between 1976 and 1997. PATIENTS: All thirty-two patients operated on for microprolactinoma were female, with a mean age of 31 years (range 16-49). Indications for surgery were intolerance of dopamine agonists in ten (31%), resistance in six (19%) and resistance and intolerance in four (12.5%). Two patients were from countries where dopamine agonists were unavailable. RESULTS: The mean pre-operative prolactin level was 2933 mU/l (range 1125-6000). All but 1 had amenorrhoea or oligomenorrhoea, with galactorrhoea in 15 (46.9%). Twenty-five (78%) were cured by trans-sphenoidal surgery, as judged by a post-operative serum prolactin in the normal range. During a mean follow-up of 70 months (range 2 months to 16 years) there was one recurrence at 12 years. Post-operatively, one patient became LH deficient, two patients became cortisol deficient and two became TSH deficient. Out of 21 patients tested for post-operative growth hormone deficiency, 6 (28.6%) were deficient. Five patients developed post-operative diabetes insipidus which persisted for greater than 6 months. There were no other complications of surgery. The estimated cost of uncomplicated trans-sphenoidal surgery, and follow-up over 10 years, was similar to that of dopamine agonist therapy. CONCLUSION: In patients with hyperprolactinaemia due to a pituitary microprolactinoma, transsphenoidal surgery by an experienced pituitary surgeon should be considered as a potentially curative procedure. The cost of treatment over a 10 year period is similar in uncomplicated cases to long-term dopamine agonist therapy.  (+info)

Mucocele involving the anterior clinoid process: MR and CT findings. (2/182)

We report two patients with surgically proved mucoceles involving the anterior clinoid process. One patient had a mucocele of an Onodi cell and the other had a mucocele isolated to the anterior clinoid process. The MR signal was increased on both T1- and T2-weighted images in the first patient but was isointense on both sequences in the second patient, a finding that resulted in misdiagnosis. The developmental and anatomic features, as well as the diagnostic pitfalls, are discussed.  (+info)

On the homology of the alisphenoid. (3/182)

The relationships of the elements of the cavum epiptericum in a hypothetical primitive mammalian precursor are reconstructed, and these are analysed in relation to the development of recent mammals, especially the fruit bat Nyctinomus johorensis. The alisphenoid in mammals is part cartilage bone, part membrane bone. The mammalian homologue of the primitive reptilian processus ascendens appears to be internal to the maxillary nerve. If so, then the 'lamina ascendens', that portion of the alisphenoid of mammals which lies between maxillary and mandibular nerves, cannot be a true processus ascendens but must be neomorphic. It is suggested that the mammalian lamina ascendens arose from an upgrowth of the root of the quadrate ramus of the epipterygoid in cynodonts, separating foramen rotundum from foramen ovale. In Ditremata the alisphenoid is completed by an element of membrane bone; this, it is suggested here, originated as the anterior lamina of the periotic in cynodonts, which is retained in monotremes. It is suggested that the alicochlear commissure of mammals originated as the later flange of the periotic in cynodonts.  (+info)

Evaluation of CSF leaks: high-resolution CT compared with contrast-enhanced CT and radionuclide cisternography. (4/182)

BACKGROUND AND PURPOSE: Radiologic evaluation of CSF leaks is a diagnostic challenge that often involves multiple imaging studies with the associated expense and patient discomfort. We evaluated the use of screening noncontrast high-resolution CT in identifying the presence and site of CSF rhinorrhea and otorrhea and compared it with contrast-enhanced CT cisternography and radionuclide cisternography. METHODS: We retrospectively reviewed the imaging studies and medical records of all patients who were evaluated for CSF leak during a 7-year period. Forty-two patients with rhinorrhea and/or otorrhea underwent high-resolution CT of the face or temporal bone and then had CT cisternography and radionuclide cisternography via lumbar puncture. The results of the three studies were compared and correlated with the surgical findings in 21 patients. RESULTS: High-resolution CT showed bone defects in 30 of 42 patients (71%) with CSF leak. High-resolution, radionuclide cisternography and CT cisternography did not show bone defects or CSF leak for 12 patients (29%) who had clinical evidence of CSF leak. Among the 30 patients with bone defects, 20 (66%) had positive results of their radionuclide cisternography and/or CT cisternography. For the 21 patients who underwent surgical exploration and repair, intraoperative findings correlated with the defects revealed by high-resolution CT in all cases. High-resolution CT identified significantly more patients with CSF leak than did radionuclide cisternography and CT cisternography, with a moderate degree of agreement. CONCLUSION: Noncontrast high-resolution CT showed a defect in 70% of the patients with CSF leak. No radionuclide cisternography or CT cisternography study produced positive results without previous visualization of a defect on high-resolution CT. CT cisternography and radionuclide cisternography may be reserved for patients in whom initial high-resolution CT does not identify a bone defect or for patients with multiple fractures or postoperative defects.  (+info)

Dysgenesis of the internal carotid artery associated with transsphenoidal encephalocele: a neural crest syndrome? (5/182)

We describe two original cases of internal carotid artery dysgenesis associated with a malformative spectrum, which includes transsphenoidal encephalocele, optic nerve coloboma, hypopituitarism, and hypertelorism. Cephalic neural crest cells migrate to various regions in the head and neck where they contribute to the development of structures as diverse as the anterior skull base, the walls of the craniofacial arteries, the forebrain, and the face. Data suggest that the link between these rare malformations is abnormal neural crest development.  (+info)

Evaluation of apical root resorption following extraction therapy in subjects with Class I and Class II malocclusions. (6/182)

The purpose of this study was to determine the amount of root resorption during orthodontic treatment, and to examine the relationship between tooth movement and apical root resorption. Twenty-seven Class I and 27 Class II patients treated with edgewise mechanics following first premolar extractions were selected. The following measurements were made on the pre- and post-treatment cephalograms: upper central incisor to palatal plane distance, the inclination of upper central incisor to the FH and AP planes, the perpendicular distances from the incisor tip to the AP and PTV planes, and incisor apex to PTV. The amount of apical root resorption of the maxillary central incisors was determined for each patient by subtracting the post-treatment tooth length from the pre-treatment tooth length measured directly on cephalograms. Intra-group differences were evaluated by the Student's t-test and inter-group differences by the Mann-Whitney U-test. For correlations the Pearson correlation coefficient was used. The results show that there was a mean of approximately 1 mm (P < 0.01) of apical root shortening in Class I patients, but in Class II division I subjects the mean root resorption was more than 2 mm (P < 0.001). The inter-group differences were statistically significant. No significant correlations were found between the amount of apical root resorption and tooth inclination, or the duration of active treatment.  (+info)

Age-related expansion and reduction in aeration of the sphenoid sinus: volume assessment by helical CT scanning. (7/182)

BACKGROUND AND PURPOSE: Aeration of the sphenoid sinus expands with the development of the sphenoid bone, but scant detailed volumetric data regarding this process, as it evolves from childhood to old age, exist. Using helical CT scanning, we assessed age-related volumetric changes of the sphenoid sinus. METHODS: We used CT data obtained from 214 patients (age range, 1 to 80 years; 111 male and 103 female subjects) with middle or inner ear disease to assess the extent of sphenoid aeration. We also determined volumes of the sphenoid sinuses on 1.0- or 1.5-mm reformatted images by integrating the sinus air (< or = -900 HU) area. RESULTS: Sphenoid sinus aeration began as a doublet in the anterior boundary of the sphenoid bone by the age of 5 years, with patients more than 6 years old exhibiting varying degrees of aeration. The aeration on both sides continued to expand until the third decade of life. The maximum average volume was 8.2 +/- 0.5 cm3. Thereafter, the volume decreased gradually, with the average volume in the seventh decade of life being 71% of the maximum level. The aeration of the peripheral portions of the sphenoid bone, such as the pterygoid process, anterior clinoid process, and dorsum sella, occurred predominantly after closure of the spheno-occipital suture, and showed a tendency to recede during aging. CONCLUSION: Volumetric assessment of the sphenoid sinus by helical CT scanning revealed age-related expansion and reduction in aeration.  (+info)

Sphenoid wing meningioma--an unusual cause of duro-optic calcification. (8/182)

Sphenoid ridge is the third commonest site of intracranial meningiomas. Although sphenoid ridge meningiomas often involve the optic canal, calcification along the optic nerve has not been reported with these tumors. We describe CT features of a calcified optic nerve in a patient with a calcified sphenoid ridge meningioma.  (+info)

Structure. The sphenoid broadly divides into the central body, the greater wings, the lesser wings, and the pterygoid process. The body of the sphenoid is the medial part of the bone, in between the two lateral greater wings. It contains a depression called the sella turcica which has a central depression for the pituitary gland. The body also houses the sphenoidal sinuses. The two lesser wings of the sphenoid are present anterior to the body and are triangular. The two greater wings of the sphenoid are also triangular in shape and are lateral to the body. The pterygoid process is directed downwards and made up of two laminae.[3][4]. Ligaments. The sphenoid bone has several intrinsic ligaments which may occasionally ossify. These are the pterygospinous, the interclinoid, and the caroticoclinoid ligaments.[5]. Openings. This cranial bone has several openings to allow entry and exit of several nerves and blood vessels to move in and out of the cranial cavity. These include the optic canal, the ...

Objective: Transsphenoidal surgery performed mainly for pituitary adenomas is known to be associated with low morbidity and mortality. Less is known about age as a risk factor which may affect outcome after transsphenoidal surgery and thus require particular attention in patients treated with this approach. This study aimed to determine the relationship of age and overall state of health with outcome and length of hospital stay after transsphenoidal surgery.. Method: Data sets of 71 consecutive patients undergoing endonasal transsphenoidal surgery between April 2010 and March 2012 were prospectively collected. Influence of age and preoperative ASA-score on outcome (GOS, transient/permanent morbidity, mortality) and length of hospital stay was analyzed.. Results: Median age of the 71 patients was 60 years (range 12-83). Patients were classified preoperatively according to ASA-score (ASA 1, n=5, 7%; ASA 2, n=52, 73%; ASA 3, n=14, 20%). The median length of hospital stay was 10 days (range 3-33 ...
The sphenoid bone has a special place within the head, situated between the brain and the face. Its major joint, the one with the occipital bone, is actually more like the ones between the vertebrae in the spine. Thus it is more flexible than are most other joints between cranial bones. In order to monitor any displacements of the sphenoid bone, check it for hinge, slide and twist. The three small pictures indicate, what is meant with these words. Occipital bone is presented in grey and the sphenoid bone in white.. Hinge: The sphenoid and occipital bones only touch at one edge of the square surface of the joint.. Slide: The surfaces of the two bones keep contact, but are sliding out of centre. Twist: The surfaces keep contact, but the bones are twisted.. ...
DISCUSSION Surgical treatment of chordomas has been challenging to neurosurgeons for many years.[9] Recently, radical resection of the tumor has been recommended for better outcomes.[2] When complete resection of the tumor is not achieved, radiation treatment for residual tumor is recommended.[1,4,7] Conventional microscopic transsphenoidal techniques have been used in the treatment of clival chordomas.[5] While performing endoscopic transsphenoidal pituitary surgeries, we have observed the panoramic anatomical exposure provided by these techniques.[3] Endoscopic transsphenoidal techniques expose the planum sphenoidale, the optic protuberances covering the optic nerves, the carotid protuberances, and the clivus as well as the sella turcica. When we encountered a patient with a tumor based at the clivus, we were convinced that the tumor could be resected using an endoscopic technique. Other surgical techniques for skull base lesions were fully discussed with the patient and his family prior to ...

A 30-year-old female has experienced amenorrhea and progressive loss of vision for four years. Physical examinations were normal except bitemporal hemianopsia revealed by ophthalmic examination. Preoperative neuroendocrine examinations showed a mild hyperprolactinemia of 72.3ng/ml (normal range, 2.8 ng/ml-29.2 ng/ml). MRI scan revealed a 31 mm 34 mm 31 mm well-circumscribed roundness mass in the suprasellar region, with intermediate signal intensity on T1-weighted images, intermediate to slightly increased signal intensity on T2-weighted images, and homogeneous enhancement with gadolinium administration with obviously homogeneous enhancement after gadolinium administration (Fig. 1). Extended endoscopic endonasal transsphenoidal approach was chosen to resect the tumor. Intraoperatively, we encountered active bleeding, however, the bleeding stopped after the tumor was completely resected. Postoperative, the patient had serious diabetes insipidus and electrolyte disturbance. Blood sodium was as ...

Introduction The temporal fossa is a significant area of the skull where elements of the facial skeleton, the skull base and the calvaria converge (Urzi et al., 2003; Williams et al., 1998). The zygomatic arch, the temporal line, the frontozygomatic processes and the supramastoid crest delineate the temporal fossa, and the temporal muscle is attached to its floor. Temporal fossae are characterized by the presence of four distinct bony elements: the frontal and parietal bones, the greater wing of the sphenoid bone, and the squamous part of the temporal bone. All of these bones are in close proximity in a region described by a small circular area termed the pterion, located approximately 4.0 cm above the zygomatic arch and 3.5 cm behind the frontozygomatic suture (Williams et al.). It occurs usually as an irregularly H-shaped meeting of sutures, forming a horizontal limb between the antero-infe rior parietal angle and the apical border of the greater sphenoid wing (Moore, 1992). The pterion is ...

A clinoidectomy, however, is not without risks. OBJECTIVE: We performed a study of diagnostic accuracy investigating whether preoperative imaging could predict tumor involvement of the clinoid, and thereby tailor the degree of bony removal. METHODS: Patients having undergone resection of a clinoid region meningioma between 2001 and 2011 were identified. Included in further analysis were those patients in whom a clinoidectomy was performed with subsequent pathologically confirmed presence or absence of tumor in the ...
Transsphenoidal Surgery. The treatment of choice for non secretory pituitary adenomas larger than 10 mm is surgical resection. Almost all pituitary adenomas can be treated initially by transsphenoidal surgery. Exceptions are tumors that are associated with a relatively small sella turcica or that have major parasellar or presellar extension. In these cases, transcranial surgery is a better approach.. The reason for frequent using of the transsphenoidal approach is the fact that complete removal of most of these tumors is impeded by cavernous sinus involvement. Tumors in the sinus cannot be removed with satisfactory morbidity by either the transcranial or the transsphenoidal approach, so the less morbid transsphenoidal resection is to be preferred.. For the transsphenoidal approach, an arterial line is usually not used, a lumbar drain is not inserted, and the patient receives hydrocortisone and antibiotics during anaesthesia induction. Approach to these tumors transnasally, carrying out the ...
Tuberculum sella meningiomas can be approached through lateral approaches including pterional/orbitozygomatic craniotomies, frontobasal craniotomy, or through expanded endoscopic transsphenoidal approaches. The authors present the case of a 60-year-old male who presented with bitemporal hemianopia and significant right-side visual acuity compromise due to a large tuberculum sella meningioma. The tumor had an important extension to the posterior fossa. A right orbitozygomatic trans-sylvian approach was deemed most suitable to tackle the posterior extension of the tumor. Some operative nuances are detailed in the video including dissection of the tumor off the carotid artery, basilar bifurcation, and small thalamoperforators attached to the tumor. Postoperatively, the patients bilateral hemianopia improved significantly, but his right visual activity remained unchanged. The remaining part of the tumor in the sella and midclivus was addressed with a second-stage expanded endoscopic transclival ...
Neurofibromatosis type I (NF 1) is an autosomal dominant disorder affecting approximately 1 in 3500 individuals. NF1 exhibits multiple manifestations such as the presence of café-au-late spots, learning disabilities and bone deformities. A large proportion of NF 1 patients display skeletal deformities including alteration in bone size and shape, the presence of scoliosis, and tendency to develop pseudoarthroses. Although the skeletal manifestations of NF1 have long been recognized and studied but only recently recognized as skeletal dysplasia by bone researchers. Craniofacial abnormality occurs in about 7% of NF1 patients and characterized by hypoplasia or absence of greater wing of sphenoid bone. This dysplasia is progressive and always unilateral, results in bulging of one eye and mid-facial bone associated with malocclusion, and is termed Sphenoid Wing Dysplasia (SWD). We have established a breeding colony of neurofibromin (NF1 gene) osteoblast conditional knockout mice. Preliminary result ...

The lateral wall of the orbit is the thickest and strongest of the orbital walls. It is composed of the zygomatic bone and the greater wing of the sphenoid bone and is separated from the lesser wing (portion of the orbital roof) by the superior orbital fissure. It is located adjacent to the middle cranial fossa and the temporal fossa and commonly extends anteriorly to the equator of the globe, helping to protect the posterior half of the eye while still allowing wide peripheral vision. Important landmarks include the following:. ...

BACKGROUND: The meningo-orbital band (MOB) is a dural structure which runs around the superior orbital fissure (SOF) tethering the frontotemporal basal dura to the periorbita, through the SOF. MOB division is important to expose and remove the anterior clinoid process, to access to proximal carotid artery and cavernous sinus area. The goal of the study was to measure how the MOB could be safely incised without cranial nerves and cavernous sinus injuries ...
The anterior pituitary gland is perfused by its portal venous system, which passes down the hypophyseal stalk. This unusual vascular supply likely contributes to the frequency of PAp. Some postulate that a gradual enlarging pituitary tumor becomes impacted at the diaphragmatic notch, compressing and distorting the hypophyseal stalk and its vascular supply. This deprives the anterior pituitary gland and the tumor itself of vascular supply, apoplectically causing ischemia and subsequent necrosis. Another theory stipulates that rapid expansion of the tumor outstrips its vascular supply, resulting in ischemia and necrosis. This explanation is doubtful, since most tumors that undergo apoplexy are slow growing.. The pituitary gland is contained in the sella turcica, which is a midline depression in the sphenoid bone. Inferiorly, the sella turcica has a thin floor of cortical bone, below which lies the air-containing sphenoid sinus. Inferior extension of an adenoma causes either remodeling of the floor ...

Radiographic findings of 15 untreated chondrosarcomas of the cranial and facial bones were reviewed. These tumors have a propensity to occur in the wall of a maxillary sinus, at the junction of sphenoid and ethmoid sinuses and vomer, and at the undersurface of the sphenoid bone. Because of its slow-growing nature, chondrosarcomas tend to be large, multilobulated, and sharply demarcated when detected. Frequent bone changes are a combination of erosion and destruction, with sharp transitional zones and absent periosteal reaction. Tumor matrix calcifications, not necessarily chondroid, are almost always present. Both CT and MR may be necessary for thorough evaluation of tumor extent. ...

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 ...

N2 - Intrasellar and sellar-suprasellar adenomas are generally removed through a transsphenoidal approach. Giant adenomas with significant suprasellar extension often require a craniotomy or combined above and below approach. The use of endoscopes has increased the visualization capacity of the transsphenoidal route and made these surgeries less invasive. In this report, we describe a novel combination of the endoscopic transsphenoidal approach with the endoscopic transventricular approach to remove a giant pituitary macroadenoma extending into the third and lateral ventricles. The tumor was initially removed via an endoscopic transnasal transsphenoidal, transtuberculum, ...

The posterior surface of the body, quadrilateral in form (fig. 349), is joined, during infancy and adolescence to the front of the basilar part of the occipital bone by a plate of cartilage, which ossifies between the eighteenth and twenty-fifth years.. The anterior surface of the body (fig. 350) presents, in the median plane, a triangular crest which forms a small part of the septum of the nose and is termed the sphenoidal crest. The anterior border of this crest articulates with the perpendicular plate of the ethmoid bone. On either side of the crest a rounded opening leads into the corresponding sphenoidal sinus. The sphenoidal sinuses are two large, irregular cavities in the body of the bone, separated from each other by a bony septum which is commonly bent to one or the other side. They vary considerably in form and size, * are seldom symmetrical, and are often partially subdivided by bony laminae. A lateral recess may extend from one or other sinus into the greater wing and lingula; the ...
The medial pterygoid plate (or medial pterygoid lamina) of the sphenoid bone is a horse-shoe shaped process that arises from its underside. It is narrower and longer than the lateral pterygoid plate and curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the tensor veli palatini glides. The lateral surface of this plate forms part of the pterygoid fossa, the medial surface constitutes the lateral boundary of the choana or posterior aperture of the corresponding nasal cavity. Superiorly the medial plate is prolonged on to the under surface of the body as a thin lamina, named the vaginal process, which articulates in front with the sphenoidal process of the palatine and behind this with the ala (wing) of the vomer. The angular prominence between the posterior margin of the vaginal process and the medial border of the scaphoid fossa is named the pterygoid tubercle, and immediately above this is the posterior opening of the pterygoid ...

The classification of maxilla fractures again follows the concept of areas of relative strength within the facial skeleton. There are three principal fracture lines which correspond to relative areas of weakness, and these are referred to as Le Fort fractures. By definition, these fractures must transect the pterygoid process of the sphenoid bone.. Le Fort I. This is a transverse fracture through the inferior maxillary antra, which separates off the alveolar process of the maxilla. The Le Fort I is demonstrated on the OM view with fractures through the medial and lateral walls of the maxillary antra, and the nasal septum.. Le Fort II. This is a pyramidal fracture, which separates off the central portion of the face. The OM radiograph identifies the Le Fort II with fractures through the lacrimal bones, medial orbital walls, infra-orbital rim and lateral walls of the maxillary antra.. Le Fort III. This fracture is characterised by separation of the entire facial skeleton from the skull. The ...
A large avidly enhancing sellar/parasellar and suprasellar mass is evident. It measures 3.9 x 3.8 x 3.1 cm. The lesion invades the sphenoid bone, filling most of the right sphenoid sinus but also involving the left. It also invades into the base of the pterygoid. process on the right and into the adjacent apex of the petrous temporal bone. Posteriorly it invades through the right side of the clivus into the prepontine cistern. High T1 signal material within the remaining sphenoid sinus may represent proteinaceous or haemorrhagic fluid. The lesion is intimately related to the right ICA, from the posterior genu of the cavernous ICA, enveloping it in the cavernous sinus (and invading the cavernous sinus) and closely related to the supraclinoid ICA to just before the bifurcation. Enhancement is still noted within the internal carotid artery. In the suprasellar region it abuts and deforms the optic chiasm and adjacentoptic nerves.

Meningiomas have been divided into three types based on their patterns of growth. Histological factors that increase the grade include a high number of mitotic figures, necrosis and local invasion. Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor. Gamma knife radiation and microscopic surgery are common options. Their encapsulated, slow growth makes meningiomas good targets for radiosurgery. In one series, less than one-third of clinoidal meningiomas could be completely resected without unacceptable risk of damaging of blood vessels (especially the carotid artery) or cranial nerves, risks that are lower with radiosurgery. If surgery is done and the entire tumor cannot be removed, then external beam radiation helps reduce recurrence of the growth. Most all meningiomas grow very slowly and almost never metastasize to other parts of the body. In part because of its slow growth, if a tumor is asymptomatic and found only by imaging, the best course is often ...

MRI and CT showed a cystic mass filling the nasopharynx with a midline bony defect in the sphenoid bone above the clivus. Posterior nasal endoscopy visualized the cystic lesion prior to surgical removal. Connection with CSF and subarachnoid space was excluded. At 6-month follow-up, developmental miletones were normal, and repeat CT showed no evidence of recurrence of the mass. Histopathology of the lesion showed choroid plexus, glial, and respiratory-like epithelial cells. [1]. COMMENT. Reviewing the literature, the authors found reports of 30 cases of pharyngeal neuroglial heterotopia. Both CT and MRI are recommended in the assessment of nasopharyngeal masses. CT visualizes any bony deformities of the skull base, and MRI detects intracranial connections through the skull defect. ...

The authors analyzed routine skull CT scans from 24 patients with no brain pathology or fractures and measured the interoptic distance at the level of the limbus sphenoidale, the chiasmatic groove sulcal length and width, and the angle of the suprasellar notch.. Indeed, the suprasellar notch was defined as the angle between 2 lines, the first passing through the tuberculum sellae midpoint and perpendicular to the cribriform plate, and a second line passing between 2 points, the midpoints of the limbus sphenoidale and the tuberculum sellae. Moreover, the authors performed on 15 cadaveric heads an endoscopic endonasal transplanum transtuberculum approach with the aid of a neuronavigator to achieve a step-by-step comparison with the radiological data. The whole CT scanning set was statistically analyzed to determine the statistical interdependency of the suprasellar notch angle with the other 3 measurements, that is, the sulcal length at the midline, the interoptic distance at the optic canal ...

Spontaneous reossification of the sellar floor after transsphenoidal surgery has been rarely reported. Strontium ranelate, a divalent strontium salt, has been shown to increase bone formation, increasing osteoblast activity. We describe an unusual case of a young patient with Cushings disease who was treated with strontium ranelate for low bone mass who experienced spontaneous sellar reossification after transsphenoidal surgery. A 21-year-old male presented with Cushings features. His past medical history included delayed puberty diagnosed at 16 years, treated with testosterone for 3 years without further work-up. He was diagnosed with Cushings disease initially treated with transsphenoidal surgery, which was not curative. The patient did not come to follow-up visits for more than 1 year. He was prescribed strontium ranelate 2 g orally once daily for low bone mass by an outside endocrinologist, which he received for more than 1 year. Two years after first surgery he was reevaluated and ...
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 ...

Planum sphenoidale and tuberculum sella meningiomas arise from the floor of the anterior cranial fossa near the midline and present with visual disturbances due to compromise of the optic nerves and chiasm necessitating surgical removal in most cases. The traditional craniotomy and open surgical removal with decompression of the optic apparatus has been effectively used for many years.. A minimally invasive cranial approach via a supraorbital incision and bone opening is also reportedly used quite effectively to remove these tumors. Another option is the endoscopic endonasal approach (EEA) that has been increasingly used for this purpose over the past decade, and in experienced hands, has proven to be a safe and effective option as well. To date, the literature is limited primarily to small single institution, retrospective studies and meta-analyses comparing outcomes between the EEA and transcranial approaches. Here are a few seminal reviews.. In 2012, Komotar et al., published a meta-analysis ...
