The 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...

Molecular 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.

Nervous system: Ependymomas

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 ...
