Nervous system: Ependymomas
نویسنده
چکیده
Ependymomas are well-delineated moderately cellular gliomas. Histolological features are perivascular pseudo rosettes and ependymal rosettes. WHO classification differentiate four major types: 1. Ependymoma and variants (grade II): Cellular ependymoma: a variant of ependymoma with conspicuous cellularity but often less prominent pseudo-rosette or rosette formation. Papillary ependymoma: a rare variant which looks like choroid plexus papilloma. Clear cell ependymoma: a rare variant which may be confused with oligodendroglioma neurocytoma or metastatic renal cell carcinoma.

Supratentorial Tanycytic Ependymoma in an Adult Male: Case Report and Review of Literature
Ependymomas, tumors of the ependymal cells, are very rare and usually present in the pediatric population. Furthermore, there are even rarer variants of ependymomas that can include cellular, papillary, clear cell, and tanycytic subtypes. We present a case of a supratentorial tanycytic ependymoma in an adult male and review the literature in regard to this rare primary central nervous system ne...
متن کاملMalignant Transformation of Grade II Ependymoma in a 2-Year-Old Child: Case Report
Ependymomas are central nervous system neoplasms that account for a third of all posterior fossa tumors in children. The most common location for infratentorial ependymoma is within the fourth ventricle. We present a case report of malignant transformation of an infratentorial grade II ependymoma in a 2-year-old child who presented with vomiting and visual disturbance. An infratentorial brain t...
متن کاملCentral nervous system tumors with ependymal features: a broadened spectrum of primarily ependymal differentiation?
Ependymomas are well-characterized central nervous system (CNS) tumors that occur most often in children and young adults. Several other CNS tumor entities, including astroblastoma, chordoid glioma, papillary tumor of the pineal region, angiocentric glioma, and pilomyxoid astrocytoma, variably display histopathologic features of ependymal differentiation. The ependymal differentiation in some o...
متن کاملThe Current Management of Intracranial Ependymomas in Children
E are relatively rare neuroepithelial tumors and account for 3-7% of all central nervous system (CNS) tumors. Among pediatric CNS tumors, ependymomas are the third most common intracranial tumor (6-14%) after juvenile pilocytic astrocytomas and primitive neuroectodermal tumors. The incidence in children is reported to be six times that in adults. Fifty percent of them occur under the age of fiv...
متن کاملMolecular alterations in ependymomas.
Ependymal tumours are uncommon neoplasms of the central nervous system. Basic molecular alterations underlying their development are not so well defined in contrast to the astrocytic tumours. We compiled literature data on the molecular changes in ependymomas to show clinical and pathological correlations and review the prognostic factors that may much better predict their clinical behaviour.
متن کاملSpinal cord ependymoma presenting with neurological deficits in the setting of trauma.
Ependymomas represent 4% of all primary central nervous system neoplasms in adults, with 30% occurring in the spinal cord. We describe a young man with neurological deficits following a motor vehicle accident who was found to have an intramedullary cervicothoracic ependymoma.
