Extra-Axial supratentorial anaplastic ependymoma: Unusual location of an aggressive tumor, A case report

Introduction: Ependymomas are more common in the pediatric population, in whom they are commonly infratentorial. Extra axial location of a supratentorial ependymoma is extremely rare. Diagnosis: Radiologically these tumors are often misdiagnosed as meningioma or other extra axial lesions owing to their unusual location and lack of any pathognomonic features. Hence, histopathological examination becomes imperative for proper evaluation and an adequate diagnosis. Case: Herein we report a case of a supratentorial extra axial anaplastic ependymoma misdiagnosed as a metastatic tumor on radiological examination and mimicking meningioma intra operatively, located in the frontal and temporal region in a 20 year old man.
