Tanycytic Ependymoma: A Challenging Histological Diagnosis [PDF]

Case Reports in Neurological Medicine, 2013
Tanycytic ependymoma is a rare form of ependymoma that usually arises in the intramedullary spine. It has a unique histology emphasized by the inconspicuous ependymal pattern of cells and close resemblance to schwannoma and astrocytoma.

A rare case report of pituitary ependymoma

Interdisciplinary Neurosurgery, 2023
Ependymomas with pituitary localization are very rare in the adult age group. As a matter of fact, to date, only 13 cases of pathologically confirmed pituitary ependymoma have been reported.

Extramedullary Conus Ependymoma Involving a Lumbar Nerve Root with Filum Terminale Attachment

Clinical Medicine Insights: Case Reports, 2015
Purpose In the current report, we describe a case of an extramedullary ependymoma involving a lumbar nerve root near conus medullaris. Spinal ependymomas commonly present as intramedullary tumors in the cervical or thoracic cord or as tumors arising from

Intraparenchymal clear cell ependymoma

Journal of Cytology, 2011
Clear cell ependymoma (CCE) is an uncommon variant of ependymoma having a predilection for the supratentorial region. Histologically, it bears an uncanny resemblance to oligodendroglioma, central neurocytoma, hemangioblastoma and metastasis from clear ...

Phase II study of intravenous etoposide in patients with relapsed ependymoma (CNS 2001 04) [PDF]

, 2022
BackgroundRelapsed ependymoma has a dismal prognosis, and the role of chemotherapy at relapse remains unclear. This study prospectively evaluated the efficacy of intensive intravenous (IV) etoposide in patients less than 21 years of age with relapsed ...

AOSNP-ADAPTR resource level-based recommendations on practical diagnostic strategies for ependymomas. [PDF]

Brain Pathol
Adapting Diagnostic Approaches for Practical Taxonomy in Resource‐Restrained Regions (ADAPTR) recommendations for ependymomas in resource‐restrained settings (RL = resource level; created in BioRender). Abstract Ependymomas are uncommon primary tumors of the central nervous system (CNS) that affect both children and adults.

Multiplatform Molecular Profiling Reveals Epigenomic Intratumor Heterogeneity in Ependymoma

Cell Reports, 2020
Summary: Ependymomas exist within distinct genetic subgroups, but the molecular diversity within individual ependymomas is unknown. We perform multiplatform molecular profiling of 6 spatially distinct samples from an ependymoma with C11orf95-RELA fusion.

A Case of Thoracic Extraspinal Extradural Tanycytic Ependymoma with Its Radiological and Histopathological Findings

Cerrahpaşa Medical Journal, 2022
Extraspinal extradural tanycytic ependymoma is a very rare variant of ependymomas that usually tends to be localized in the spinal cord. We report a case of a 52-year-old woman presenting with back pain because of extraspinal extradural tanycytic ...

Clinically aggressive pediatric spinal ependymoma with novel MYC amplification demonstrates molecular and histopathologic similarity to newly described MYCN-amplified spinal ependymomas

Acta Neuropathologica Communications, 2021
Primary spinal cord tumors contribute to ≤ 10% of central nervous system tumors in individuals of pediatric or adolescent age. Among intramedullary tumors, spinal ependymomas make up ~ 30% of this rare tumor population.

Trisomy 19 ependymoma, a newly recognized genetico-histological association, including clear cell ependymoma [PDF]

, 2007
Ependymal tumors constitute a clinicopathologically heterogeneous group of brain tumors. They vary in regard to their age at first symptom, localization, morphology and prognosis. Genetic data also suggests heterogeneity.
