The occurrence of cerebellopontine angle (CPA) medulloblastoma is a rare phenomenon. We report such a case in a 19-year-old girl who had 6th and 8th cranial nerve palsies as well as cerebellar dysfunction. The tumour arose from the left flocculus or adjacent cerebellar hemisphere and projected into the CPA. She was treated by subtotal removal of the tumour, followed by entire neuroaxis irradiation and immunochemotherapy. The clinical characteristics and pathogenesis of CPA medulloblastoma are reviewed and discussed.
桥小脑角（CPA）髓母细胞瘤的发生是一种罕见现象。我们报告了一例19岁女孩的此类病例，她患有第6和第8颅神经麻痹以及小脑功能障碍。肿瘤起源于左侧绒球或相邻的小脑半球，并突入CPA。她接受了肿瘤次全切除治疗，随后进行了全神经轴照射和免疫化疗。本文对CPA髓母细胞瘤的临床特征和发病机制进行了综述和讨论。
