Abstract
|
|
|
|
Ependymomas are rare neuroepithelial tumors that arise from the ependymal cells of the cerebral ventricles, the central canal of the spinal cord and cortical rests. Some tumors may extend to the gray matter reaching the pial surface, but pure cortical ependymomas are uncommon. We report a case of ependymoma arising from extraventricular system, especially supratentorial falx. Sixty five-year-old woman presented memory impairment and apraxia was admitted to the our clinic. Magnetic resonance imaging (MRI) of the brain showed a 4.5×5.5 cm sized mass in the left occipital lobe, attached to the falx. The patient underwent the total tumor removal and the final pathology showed grade II cellular ependymoma. Because of the supratentorial and pure cortical ependymomas are rare, proper studies and pathologic confirm are needed to distinguish different tumors.
