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.
迄今为止仅报告了33例，髓母细胞瘤完全位于小脑脑桥（CP）角的轴外位置是非常罕见的。我们报告了一例15岁男性儿童位于CP角的轴外髓母细胞瘤病例，该病例最初被临时诊断为神经鞘瘤并接受了手术治疗。通过常规苏木精和伊红染色以及免疫组化标记物进行了髓母细胞瘤的组织病理学诊断。本病例报告强调了一个事实，即尽管极为罕见，但轴外肿块为髓母细胞瘤的可能性确实存在。
