Supratentorial extra-axial anaplastic ependymoma mimicking a meningioma

摘要

Ependymomas account for 1.9% of all primary brain tumors and 3.1 % of all gliomas Extra-axial supratentorial ependymomas (EASE) are radiologically similar to meningiomas, and are rare with only five cases reported [Table 1]. We report a case in the subarachnoid, plane, the radiological features of which mimicked a falx meningioma.
