Frontal Lobe Ependymoma: A Case Report

A 15-year-old female patient with no previous health problems was admitted our clinic with syncope. Cranial computed tomography of the patient showed a 6.5x3.5 cm mass lesion with heterogeneous weak hyperdensity in the left frontoparietal region adjacent to the internal tabula. There was a hypodense zone of edema around the lesion. Following contrast medium injection, significant contrast enhancement was observed. In the anterior portion of the body of the left lateral ventricle and in the left frontal horn, we found obliteration which was secondary to the edema. The mass was excised by left frontotemporal craniotomy. Histopathological findings were found to be consistent with ependymoma, WHO Grade III. We discuss here a case with a diagnosis of an ependymoma with an extraaxial location and anaplastic histomorphology, in the light of current literature.
