Preferred Label : ependymal tumor;
RADLEX synonyms : ependymoma;
Definition : Glioma derived from ependymocytes that tend to present as malignant intracranial tumors
in children and as benign intraspinal neoplasms in adults. It may arise from any level
of the ventricular system or central canal of the spinal cord. Intracranial ependymomas
most frequently originate in the fourth ventricle and histologically are densely cellular
tumors which may contain ependymal tubules and perivascular pseudorosettes. Spinal
ependymomas are usually benign papillary or myxopapillary tumors. (From DeVita et
al., Principles and Practice of Oncology, 5th ed, p2018; Escourolle et al., Manual
of Basic Neuropathology, 2nd ed, pp28-9) [MeSH];
