With only 33 cases reported so far, a purely extra-axial position of medulloblastoma at cerebellopontine (CP) angle is quite exceptional. We report a case of extra-axial medulloblastoma in a 15-year-old male child located in the CP angle that was surgically treated with a provisional diagnosis of schwannoma. Histopathological diagnosis of medulloblastoma was made with the routine hematoxylin and eosin stain and immunohistochemical markers. This case report highlights the fact that although extremely rare, the possibility of an extra-axial mass being a medulloblastoma does exist.
