ependymomas accounts for about 2%–6% of cns and 60%–70% of spinal cord tumors. several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. in spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. this report presents a case of giant cell ependymoma...

Abstract Ependymomas are rare tumors originating from neuroepithelial cells lining the wall of ventricles or central canal spinal cord.

Ependymoma is a type of glial tumor that arises from the ependymal lining of the ventricular system of the central nervous system. These tumors may present as a rare extraspinal variety at the sacrococcygeal region, and may be misdiagnosed as pilonidal disease in the post-sacral area or present with mass-effect symptoms on the bowel or bladder in the pre-sacral region. This is a case of soft ti...

ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...
