Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS. (From Devita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072; J Neurosurg 1998 Mar;88(3):521-8)
A villous structure of tangled masses of BLOOD VESSELS contained within the third, lateral, and fourth ventricles of the BRAIN. It regulates part of the production and composition of CEREBROSPINAL FLUID.
A usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged CHOROID PLEXUS, which may be associated with oversecretion of CSF. The tumor usually presents in the first decade of life with signs of increased intracranial pressure including HEADACHES; ATAXIA; DIPLOPIA; and alterations of mental status. In children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. Malignant transformation to choroid plexus carcinomas may rarely occur.

The thin, highly vascular membrane covering most of the posterior of the eye between the RETINA and SCLERA.
The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.
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.
A watery fluid that is continuously produced in the CHOROID PLEXUS and circulates around the surface of the BRAIN; SPINAL CORD; and in the CEREBRAL VENTRICLES.
One of two ganglionated neural networks which together form the ENTERIC NERVOUS SYSTEM. The myenteric (Auerbach's) plexus is located between the longitudinal and circular muscle layers of the gut. Its neurons project to the circular muscle, to other myenteric ganglia, to submucosal ganglia, or directly to the epithelium, and play an important role in regulating and patterning gut motility.

The three membranes that cover the BRAIN and the SPINAL CORD. They are the dura mater, the arachnoid, and the pia mater.
Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.
A complex network of nerve fibers including sympathetic and parasympathetic efferents and visceral afferents. The celiac plexus is the largest of the autonomic plexuses and is located in the abdomen surrounding the celiac and superior mesenteric arteries.
The lumbar and sacral plexuses taken together. The fibers of the lumbosacral plexus originate in the lumbar and upper sacral spinal cord (L1 to S3) and innervate the lower extremities.
A network of nerve fibers originating in the upper four CERVICAL SPINAL CORD segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head. It also distributes motor fibers to muscles of the cervical SPINAL COLUMN, infrahyoid muscles, and the DIAPHRAGM.
Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.

Imaging features of intraventricular melanoma. (1/71)

We present the MR imaging findings in a patient with symptoms of increased intracranial pressure and a mass in the left lateral ventricle. The mass showed increased signal intensity on T1-weighted images and low signal intensity on T2-weighted images. The histologic diagnosis was that of melanoma, and detailed physical and funduscopic examinations disclosed no evidence of a primary lesion. We believe that the mass was a primary intraventricular melanoma, possibly arising from the choroid plexus, and we discuss the mechanisms that may be responsible for its occurrence in this location.  (+info)

Choroid plexus papilloma of cerebellopontine angle with extension to foramen magnum. (2/71)

A case of choroid plexus papilloma resembling meningioma of cerebellopontine (CP) angle with its extension to foramen magnum is presented. Occurrence of this tumour in CP angle is very rare. Its extension towards foramen magnum is further rare. It was a real diagnostic enigma preoperatively as the tumour was resembling meningioma upto some extent on radiological study. Retromastoid craniectomy with microsurgical excision of tumour and its extension was achieved in toto. Tumour was attached to few rootlets of lower cranial nerves which were preserved. Attachment of the tumour with lower cranial nerves again caused diagnostic confusion with neurofibroma intraoperatively.  (+info)

Cytotoxic T-lymphocyte epitope immunodominance in the control of choroid plexus tumors in simian virus 40 large T antigen transgenic mice. (3/71)

The simian virus 40 (SV40) large tumor antigen (Tag) is a virus-encoded oncoprotein which is the target of a strong cytotoxic T-lymphocyte (CTL) response. Three immunodominant H-2(b)-restricted epitopes, designated epitopes I, II/III, and IV, have been defined. We investigated whether induction of CTLs directed against these Tag epitopes might control Tag-induced tumors in SV11(+) (H-2(b)) mice. SV11(+) mice develop spontaneous tumors of the choroid plexus due to expression of SV40 Tag as a transgene. We demonstrate that SV11(+) mice are functionally tolerant to the immunodominant Tag CTL epitopes. CTLs specific for the H-2Kb-restricted Tag epitope IV were induced in SV11(+) mice following adoptive transfer with unprimed C57BL/6 spleen cells and immunization with recombinant vaccinia viruses expressing either full-length Tag or the H-2Kb-restricted epitope IV as a minigene. In addition, irradiation of SV11(+) mice prior to adoptive transfer with unprimed C57BL/6 spleen cells led to the priming of epitope IV-specific CTLs by the endogenous Tag. Induction of epitope IV-specific CTLs in SV11(+) mice by either approach correlated with increased life span and control of the choroid plexus tumor progression, indicating that CTLs specific for the immunodominant Tag epitope IV control the progressive growth of spontaneous tumors induced by this DNA virus oncogene in transgenic mice.  (+info)

Cytokeratin 7 and 20 expression in choroid plexus tumors: utility in differentiating these neoplasms from metastatic carcinomas. (4/71)

Tumors derived from choroid plexus epithelium are uncommon and may exhibit a wide variety of histologic patterns. They often are difficult to distinguish from metastatic carcinomas. Previous studies that addressed this issue yielded conflicting results. Recent reports have demonstrated that evaluation of coordinate expression of cytokeratin (CK) 7 and CK20 aids in distinguishing primary from metastatic lesions in a number of anatomic sites and that tumors that commonly are metastatic to the brain retain their CK7/CK20 immunophenotype in this location. We examined 35 choroid plexus tumors with a panel of antibodies to determine their CK7/CK20 immunophenotype. Tumors from 35 patients (7 male, 28 female; mean age, 25 years), including 31 choroid plexus papillomas and 4 atypical papillomas, were evaluated. All tumors were intraventricular or within the cerebellopontine angle and composed predominantly of orderly columnar epithelial cells resting on distinct fibrovascular cores. Atypical papillomas contained combinations of focal loss of architectural pattern, increased mitotic activity, necrosis, and brain parenchymal invasion. No lesion was unequivocally malignant. Twenty-six tumors (74%), including all atypical papillomas, were CK7 positive and CK20 negative. Two tumors stained with both markers, one stained with CK20 only, and six stained with neither marker. Other findings included expression of glial fibrillary acidic protein in 24 tumors, S-100 protein in 19 tumors, transthyretin in 31 tumors, Ber EP4 in 1 tumor, CAM5.2 in 33 tumors, epithelial membrane antigen in 4 tumors, and pancytokeratin in 27 tumors. Our results indicate that the majority of choroid plexus tumors have a CK7-positive/CK20-negative immunophenotype. This finding may be useful in differentiating these lesions from metastatic carcinomas that have differing CK7/CK20 profiles.  (+info)

IL-12 treatment of endogenously arising murine brain tumors. (5/71)

A number of recent studies have indicated that T cells can be stimulated to attack transplanted brain tumors in rodent models. As IL-12 has been shown to activate cytotoxic T cell responses, we tested the idea that it might stimulate a T cell response against endogenous brain tumors that arise in SV40 large T Ag transgenic mice (SV11). SV11 mice develop tumors of the choroid plexus, a specialization of the ependymal lining of the brain ventricles. They are a particularly relevant model of human disease, because they are immunocompetent but immunologically tolerant of the tumors. SV11 mice were treated with recombinant murine IL-12 for 10 days. Tumors grew more slowly than in control treated mice, and in some cases were reduced in size, as assessed by magnetic resonance imaging before and after treatment. At the end of treatment, tumors, but not brain parenchyma, exhibited extensive infiltration of activated CD8(+) and CD4(+) T cells. Tumors also showed a reduction in vascular density. Mice treated with IL-12 lived significantly longer than control mice. Tumors that progressed were nearly devoid of T cells, indicating that the T cell response was not sustained. In addition, some mice that had a substantial tumor burden at the beginning of treatment displayed evidence of immunosuppression, which might be related to TGF-ss2 detected in tumors. We conclude that IL-12 treatment can initiate an anti-tumor response even against endogenously arising brain tumors, but factors that will allow a sustained and more effective anti-tumor response need to be determined.  (+info)

Prostaglandin D synthase (beta-trace) in meningeal hemangiopericytoma. (6/71)

The level of prostaglandin D synthase (PGDS), a major protein constituent of cerebrospinal fluid (CSF), is altered in various brain diseases, including meningitis. However, its role in the brain remains unclear. PGDS is mainly synthesized in the arachnoid cells, the choroid plexus and oligodendrocytes in the central nervous system. Among brain tumors, meningiomas showed intense immunoreactivity to PGDS in the perinuclear region. Thus, PGDS has been considered a specific cell marker of meningioma. In this study, we examined 25 meningeal hemangiopericytomas (HPCs) and found that 16 of the tumors (64%) showed immunoreactivity for PGDS in the perinuclear region. For comparison, 15 meningiomas, 14 soft-tissue HPCs, 1 mesenchymal chondrosarcoma, 3 choroid plexus papillomas, and 7 oligodendrogliomas were also examined. Meningiomas showed positive immunoreactivity for PGDS in 13 cases (80%). Except for one case located at the sacrum, none of the other soft-tissue HPCs showed immunostaining for PGDS. Mesenchymal chondrosarcoma arises in the bones of the skull, and its histological pattern resembles that of HPC; however, it showed no immunoreactivity for PGDS. Neither choroid plexus papillomas nor oligodendrogliomas were immunopositive for PGDS. These findings suggest that meningeal HPCs may have a unique molecular phenotype that is distinct from that of the soft-tissue HPCs. The origin of meningeal HPCs may be more closely related to the arachnoid cells.  (+info)

Tissue-specific expression of SV40 in tumors associated with the Li-Fraumeni syndrome. (7/71)

Inactivation of wild-type p53 tumor suppressor function is the primary mechanism of tumor initiation in Li-Fraumeni syndrome (LFS) individuals with germline p53 mutations. Tumors derived from LFS patients frequently retain the normal p53 allele, suggesting that alternative mechanisms in addition to gene deletion must be involved in inactivating wild-type p53 protein. DNA tumor viruses, such as SV40, target p53 for inactivation through the action of viral oncoproteins. We studied the probands from two unrelated LFS families, each of whom presented with multiple malignant neoplasms. Patient 1 developed an embryonal rhabdomyosarcoma (RMS) and a choroid plexus carcinoma (CPC), while patient 2 developed a CPC and subsequently presented with both an osteosarcoma (OS) and renal cell carcinoma (RCC). We utilized DNA sequence analysis and immunohistochemistry to determine p53 gene status in the germline and tumors, as well as evidence for SV40 T-antigen oncoprotein expression. Each patient harbored a heterozygous germline p53 mutation at codons 175 and 273, respectively. In patient 1, the normal p53 gene was lost while the mutant p53 allele was reduced to homozygosity in the RMS. Both normal and mutant genes were maintained in the CPC. In patient 2, normal and mutant p53 alleles were retained in both the CPC and RCC. Both specific PCR and immunostaining detected SV40 T-antigen in both CPCs and the RCC. In addition to chromosomal alterations, epigenetic mechanisms may disrupt p53 function during tumorigenesis. In two LFS patients, we found SV40 DNA sequences and viral T-antigen expression that could account for inactivation of the normal p53 protein. Inactivation of p53 or other tumor suppressors by viral proteins may contribute to tumor formation in specific tissues of genetically susceptible individuals.  (+info)

Cytogenetics and molecular genetics of childhood brain tumors. (8/71)

Considerable progress has been made toward improving survival for children with brain tumors, and yet there is still relatively little known regarding the molecular genetic events that contribute to tumor initiation or progression. Nonrandom patterns of chromosomal deletions in several types of childhood brain tumors suggest that the loss or inactivation of tumor suppressor genes are critical events in tumorigenesis. Deletions of chromosomal regions 10q, 11 and 17p, and example, are frequent events in medulloblastoma, whereas loss of a region within 22q11.2, which contains the INI1 gene, is involved in the development of atypical teratoid and rhabdoid tumors. A review of the cytogenetic and molecular genetic changes identified to date in childhood brain tumors will be presented.  (+info)

Choroid plexus carcinoma or choroid plexus tumor is a type of cancerous tumor that occurs in the brains choroid plexus tissue and most often occurs in children. The choroid plexus tissue lines the ventricles of the brain and produces cerebrospinal fluid or CSF. CSF circulates around the brain and spinal cord providing cushioning and protection. Because these tumors arise from the tissue involved in the making of CSF, the tumors can spread widely through this fluid. Symptoms of choroid plexus carcinoma are similar to those of other brain tumors including frequent headaches, unusually large head due to excess fluid on the brain, or large soft spots found on the babys head. Other symptoms may include a decrease or loss of appetite and vomiting. The cause behind these tumors is largely unknown.. Treatment is usually surgical removal of the tumor and if removed completely, may be the only treatment necessary. If the recurs, a second surgery along with radiation and/or chemotherapy may be needed. ...
Answer: Choroid plexus papilloma. Histology: This papillary neoplasm is composed of delicate fibrovascular stalks that are lined by a single layer of bland appearing cuboidal to columnar epithelium with round to oval, basally situated monomorphic nuclei. No mitotic figures are readily identified. These features are diagnostic of a choroid plexus papilloma. Discussion: Choroid plexus tumors make up less than 1% of all brain tumors, but they represent 2-4% of brain tumors in children, and 10-20% of brain tumors in the first year of life. In general, choroids plexus papillomas are five times more common than choroids plexus carcinomas. Approximately 80% of choroid plexus carcinomas arise in children representing 20-40% of pediatric choroid plexus tumors. The majority of choroids plexus tumors arise in the lateral ventricle (50%), followed by the fourth (40%) and third ventricles (5%).. Histologically, the differential diagnosis of choroids plexus papilloma includes villous hyperthrophy (diffuse ...

Choroid plexus carcinomas (CPCs) are rare, aggressive pediatric brain tumors with no established curative therapy for relapsed disease, and poor survival rates. TP53 Mutation or dysfunction correlates with poor or no survival outcome in CPCs. Here, we report the case of a 4 month-old female who presented with disseminated CPC. After initial response to tumor resection and adjuvant-chemotherapy, the tumor recurred and metastasized with no response to aggressive relapse therapy suggesting genetic predisposition. This patient was then enrolled to a Molecular Guided Therapy Clinical Trial. Genomic profiling of patient tumor and normal sample identified a TP53 germline mutation with loss of heterozygosity, somatic mutations including IDH2, and aberrant activation of biological pathways. The mutations were not targetable for therapy. However, targeting the altered biological pathways (mTOR, PDGFRB, FGF2, HDAC) guided identification of possibly beneficial treatment with a combination of sirolimus, thalidomide,
Postoperative imaging important: The first postoperative imaging should be done within 72 hours to make sure there is no residual tumor or to assess its size if tumor remains. Follow-up imaging will then depend on the pathology of the tumor and on the adjuvant therapies (typically every 3 months for choroid plexus carcinomas; and every 6 months, then every year for choroid plexus papillomas ...

Choroid plexus papillomas are benign, slow-growing tumours. They are usually treated by surgery alone. These types of tumours often block the flow of cerebrospinal fluid (CSF), causing a buildup of CSF in the brain (hydrocephalus). Sometimes, removing the tumour will not relieve the fluid buildup an
Choroid plexus carcinoma mouse model. TgT121;p53+/− mice develop focally aggressive angiogenic CPC that is histologically detectable by 8 weeks and terminal by 12 weeks of age ( 7, 22). Often, a single animal develops multiple focal tumors. Tumors are initiated by choroid plexus-specific expression of T121, an NH2-terminal fragment of SV40 large T antigen that binds and inactivates the tumor suppressor pRb and related proteins p107 and p130 ( 22). T121 induces cell proliferation and p53-dependent apoptosis throughout the choroid plexus epithelium such that heterozygosity for a p53 null allele facilitates multifocal tumor progression to CPC with complete p53 loss. Histologic analyses show that the timing and penetrance of tumor development is highly reproducible ( 6). CPC tumors are heavily vascular lesions and thus provide an ideal tumor type in which to study the effect of antiangiogenic agents in experimental animals.. A total of 20 mice were studied, including 11 TgT121;p53+/− mice and ...

Several primary pathologic entities in diverse anatomic locations have the potential to simulate metastatic neoplasms histologically. Their misinterpretation as such may result in needless and extensive clinical evaluations that are intended to detect a presumed malignancy at another site.

This is the last in my tumor biomarker series -- at least until future significant biomarkers are established. I conclude this series with a short description of INI1, a marker for atypical teratoid/rhabdoid tumor (AT/RT). A clinically aggressive embryonal tumor of infancy, AT/RT is characterized by mutations in SMARCB1/INI1 (HSNF5). Immunohistochemical evaluation of AT/RT for the INI1 protein using the BAF47 antibody shows a loss of labelling in tumor cell nuclei, with retention of staining in internal positive control cells such as endothelial cells. Since AT/RT has morphologic overlap with medulloblastoma, CNS PNET, choroid plexus carcinoma, GBM, and other malignant tumors of childhood, INI1 immunohistochemistry is extremely useful in arriving at a diagnosis of AT/RT. A diagnosis of AT/RT carries implications for genetic counseling as this tumor -- in about a one-third of cases -- is a component of the rhabdoid tumor predisposition syndrome (RTPS) wherein there is a germline mutation of ...
Atypical teratoid rhabdoid tumors (ATRTs) are a rare pediatric brain tumor with high mortality rate. Several large series have reported achieving gross-total resection (GTR) in less than 50% of patients due to the lesions large size, vascularity, and limited blood volume in young patients. While neoadjuvant chemotherapy for choroid plexus carcinomas in pediatric patients has become widely accepted, it has not been used as widely for other pediatric brain tumors. To the best of the authors knowledge, there are only 3 published cases of neoadjuvant chemotherapy for ATRTs. In the present report, the authors present a fourth case of neoadjuvant chemotherapy for ATRT and review the available literature on this strategy. A 17-month-old child presented with a left ventricular ATRT for which imaging raised concern for a highly vascularized tumor. The authors undertook neoadjuvant chemotherapy with 2 cycles of Head Start II therapy, which reduced the size of the ventricular tumor by 35% and decreased ...

Intraventricular tumors can be categorized into those that originate from structures within the ventricular system or those that arise from the ventricular wall and subsequently grow into the ventricle (2, 11). Choroid plexus tumors and meningiomas are typical examples of tumors arising from an intraventricular structure, the choroid plexus (12, 13). By contrast, intraventricular gliomas likely originate from a paraventricular location before growth into the ventricle. Regardless of origin, a tumor is considered intraventricular if it is located primarily within the ventricular system and causes a local expansion of the ventricle with growth. Most lateral ventricular tumors enlarge slowly and typically do not cause symptoms until reaching a size large enough to cause obstructive hydrocephalus or compression of surrounding eloquent structures (4, 5). The most common symptom is headache, followed by visual deficits and signs of elevated intracranial pressure, including papilledema (2, 4, 11, 12, ...
BACKGROUND. Meningiomas are the most common brain tumor in both cats and dogs. Other brain tumors include lymphoma, ependymoma, choroid plexus tumors, and glial tumors such as astrocytoma. Brain tumors rarely metastasize and the major challenge in treating brain tumors is preserving neurologic function and preventing local tumor recurrence.. DIAGNOSIS. Advanced imaging is required for the diagnosis and localization of brain tumors. MRI is preferred but CT scans can also be useful.. TREATMENT. Surgical excision alone is recommended for the treatment of meningioma in cats, while a combination of surgical excision and radiation therapy is preferred for dogs with meningioma. Anesthetic management is very important for the success of brain tumor surgery and postoperative hospitalization can be prolonged during recovery.. The combination of surgery and radiation therapy is recommended for other types of brain tumors. Chemotherapy may provide some palliative benefit for cats with lymphoma and dogs with ...

They represent 2-5% of all primary brain tumors in children, with almost 90% occurring in children less than five years old. In children, they usually arise in the trigone of the lateral ventricle. In adults they commonly arise in the fourth ventricle. Less than 10% occur in the third ventricle or elsewhere. Patients usually present with hydrocephalus. CPPs typically enhance dramatically following contrast administration on CT or MRI. Parenchymal invasion with edema may occur. Imaging findings are not

Choroid plexus blood flow was measured in adult female sheep using the radioactive microsphere technique. The response of choroid plexus, renal and cortical blood flow to the infusion of dopamine (11 sheep), haloperidol (7 sheep) and propranolol (6 sheep) were compared. Choroid plexus and renal blood flow significantly increased after dopamine infusion (55% and 49% respectively). Choroid plexus and renal blood flow decreased significantly following haloperidol infusion (-24% and 29% respectively). Cortical blood flow did not significantly change. Propranolol infusion did not significantly change blood flow in these regions. These observations suggest that dopaminergic mechanisms play a role in the regulation of choroid plexus as well as renal blood flow.
Chronic systemic inflammation triggers alterations in the central nervous system that may relate to the underlying inflammatory component reported in neurodegenerative disorders such as multiple sclerosis and Alzheimers disease. However, it is far from being understood whether and how peripheral inflammation contributes to induce brain inflammatory response in such illnesses. As part of the barriers that separate the blood from the brain, the choroid plexus conveys inflammatory immune signals into the brain, largely through alterations in the composition of the cerebrospinal fluid. In the present study we investigated the mouse choroid plexus gene expression profile, using microarray analyses, in response to a repeated inflammatory stimulus induced by the intraperitoneal administration of lipopolysaccharide every two weeks for a period of three months; mice were sacrificed 3 and 15 days after the last lipopolysaccharide injection. The data show that the choroid plexus displays a sustained response to

Background The choroid plexuses will be the interface between the blood and the cerebrospinal fluid (CSF) contained within the ventricular spaces of the central nervous system. are indicated early during development. Overall perinatal manifestation levels of genes involved in drug rate of metabolism and antioxidant mechanisms are similar to, or higher than levels measured in adults. A similar developmental pattern was observed for multispecific efflux transporter genes of the and superfamilies. Manifestation of all these genes was Trifolirhizin more variable in choroid plexus from fifteen-day-old embryos. A large panel of transcription factors involved in the xenobiotic- or cell stress-mediated induction of detoxifying enzymes and transporters is also expressed throughout development. Conclusions This transcriptomic analysis suggests relatively wellCestablished neuroprotective mechanisms in the blood-CSF barrier throughout development of the rat. The manifestation of many transcription factors ...

Choroid plexus cysts (CPCs) are cysts that occur within choroid plexus of the brain. The brain contains pockets or spaces called ventricles with a spongy layer of cells and blood vessels called the choroid plexus. This is in the middle of the fetal brain. The choroid plexus has the important function of producing cerebrospinal fluid. The fluid produced by the cells of the choroid plexus fills the ventricles and then flows around the brain and the spinal cord to provide a cushion of fluid around these structures. CPCs can form within this structure and come from fluid trapped within this spongy layer of cells, much like a soap bubble or a blister. CPCs are often called soft signs or fetal ultrasound markers because some studies have found a weak association between CPCs and fetal chromosome abnormalities. It is believed that many adults have one or more tiny CPCs. The fetal brain may create these cysts as a normal part of development. They are temporary and usually are gone by the 32nd week ...
Genetic disruption of slc4a10, which encodes the sodium-dependent chloride/bicarbonate exchanger Ncbe, leads to a major decrease in Na+-dependent HCO3− import into choroid plexus epithelial cells in mice and to a marked reduction in brain intraventricular fluid volume. This suggests that Ncbe functionally is a key element in vectorial Na+ transport and thereby for cerebrospinal fluid secretion in the choroid plexus. However, slc4a10 disruption results in severe changes in expression of Na+,K+-ATPase complexes and other major transport proteins, indicating that profound cellular changes accompany the genetic manipulation. A tandem mass tag labeling strategy was chosen for quantitative mass spectrometry. Alterations in the broader patterns of protein expression in the choroid plexus in response to genetic disruption of Ncbe was validated by semi-quantitative immunoblotting, immunohistochemistry and morphometry. The abundance of 601 proteins were found significantly altered in the choroid plexus from

A 23-year-old primigravida presented to her local hospital with reduced fetal movements at 31 week of gestation. An admission cardiotocograph showed sinusoidal pattern. An ultrasound (US) revealed a brain abnormality with a mass. An US at the regional Fetal Medicine unit confirmed a hydropic fetus, with an intracranial mass measuring 6.6×7 cm in the right lateral ventricle (possibly haemorrhagic), ventriculomegaly and loss of anatomical landmarks in the brain. Antenatal MRI scan confirmed a 7 cm mass with appearances suggestive of an intraventricular tumour, possibly choroid plexus papilloma or carcinoma. Following counselling by the multidisciplinary fetal medicine team the couple opted for termination of pregnancy and a vaginal delivery, the first such report in the literature. Cephalocentesis was performed following fetocide to reduce the hydrocephalus. Postmortem, histology, cytology and immunohistochemistry confirmed a Glioblastoma (WHO Grade IV).. The incidence of brain tumours in first ...
Glioma: Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)
Choroid plexus cyst. Ultrasound scan of a foetus brain with a choroid plexus cyst (CPC). The choroid plexus is a layer of cells and blood vessels at the centre of the foetal brain. It produces a fluid, called cerebrospinal fluid, that flows around the brain and provides a protective cushion for it against impacts. CPCs in foetuses are temporary bubbles of trapped fluid that are usually gone by the 32nd week of pregnancy. They are classed as markers for underlying chromosome abnormalities in the foetus. Ultrasound scanning is a diagnostic technique that sends high-frequency sound waves into the body via a transducer. The returning echoes are recorded and used to build an image of an internal structure. - Stock Image M130/1007
Glioblastoma represents 15%-20% of all intracranial tumors and approximately 50 % of gliomas in adults. Although capable of arising anywhere in the central nervous system, these tumors mainly present as a frontotemporal lesion (63%) of the cerebral cortex. But, intraventricular glioblastoma is rare and only few cases have been reported in the literature. We report a case of 40-year-old woman who had a headache, vomiting and visual disturbances that persisted for four weeks. Magnetic resonance imaging showed an intraventricular lesion with inhomogeneous enhancement and infiltrative borders. These characteristics are consistent with other differential diagnoses: carcinomas, ependymomas and choroid plexus papillomas. The patient underwent a stereotactic biopsy allowed the final diagnosis of intra ventricular glioblastoma.
