Fine needle aspiration cytology of myxopapillary ependymoma: a case report

, 1998
BACKGROUND: Myxopapillary ependymoma is a variant of ependymoma that usually occurs in the sacrococcygeal region. Histologically, it is characterized by arborizing papillary fronds of capillaries with mucinous stroma rimmed by ependymal cells.

Natural Course of Myxopapillary Ependymoma: Unusual Case Report and Review of Literature

, 2019
Background: Spinal cord ependymomas are the most frequent primary intramedullary tumors of the cord in middle age (40–60 years of age). Myxopapillary ependymomas are low-incidence tumors and occur in the cauda equina and conus medullaris.

Giant metastatic mixed-type spinal ependymoma presenting with hydrocephalus

Radiology Case Reports
Ependymomas are rare nervous system tumors that can arise anywhere in the neuraxis. While having a high propensity for leptomeningeal dissemination, retrograde dissemination (from the spine to the CNS) remains infrequent.
