Ependymomas are glial tumors derived from ependymal cells lining the ventricles and the central canal of the spinal cord. It may occur outside the ventricular structures, representing the extraventicular form, or without any relationship of ventricular system, called ectopic ependymona. Less than fifteen cases of ectopic ependymomas were reported and less than five were anaplastic. We report a ...

Supratentorial cortical ependymoma (CE), a rare type of ependymoma, is located in the superficial cortex. We reported 11 patients (six female and five male) with CE. The age of the patients ranged from 2 to 63 years old with a median age of 47 years at the time of diagnosis. On MRI, enhancement was noted in all cases with solid appearance in six cases, and solid and cystic appearance in five ca...

Spinal ependymomas comprise ~60% of all intramedullary tumors in adults. Ependymomas demonstrate distinct imaging features, such as central location within the spinal cord, symmetrical expansion, intra- and extratumoral cysts, hemosiderin caps, and strong enhancement on contrast-injected, T1-weighted magnetic resonance (MR) imaging. In adults, most ependymomas are myxopapillary, and in children...

Background: Subependymomas are slow-growing, benign ependymal neoplasms histologically characterized as grade I tumors. On the other hand, ependymomas are higher-grade tumors of neuroectodermal origin that share a predilection for the fourth ventricle. Given that these tumors can occur simultaneously as mixed lesions, features that raise clinical suspicion of a combined pathology warrant surgic...

Most of the spinal ependymomas are confirmed within the dura and become clinically evident by compression of the spinal cord and nerve roots of the cauda equine 1. Rarely an ependymoma may arise in the bone or soft tissues of the pelvis or sacral subcutaneum 2-4. We report a case of extraspinal ependymoma involving the lumbosacral region of the spine. A 27-year old man admitted with a history o...
