Abstract :
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 central nervous system tumors. We present a unique case of an anaplastic cortical ependymomain a 48-year-old man. The patient presented with transient amnesia and right weakness and seizure. This tumor was located in the left parieto-occipital region with extension to corpus callosum and thalamus. Microscopy and immunohistochemistry showed grade III differentiation ependymoma
