Primary central nervous system lymphoma (PCNSL) is an uncommon extranodal manifestation of non-Hodgkin's lymphoma with those presenting at the cerebellopontine angle (CPA) being rare presentations with limited reported cases in the literature. We report a 60-year old female presenting with PCNSL of the left CPA radiologically mimicking a trigeminal schwannoma with corresponding clinical signs. Imaging showed a left CPA lesion that was biopsied and confirmed as diffuse large B-cell lymphoma. Given its rarity, PCNSL should be considered in the differential diagnosis for all CPA tumours.
原发性中枢神经系统淋巴瘤（PCNSL）是非霍奇金淋巴瘤一种不常见的结外表现，而发生于桥小脑角（CPA）的病例较为罕见，文献报道的病例有限。我们报告一例60岁女性，其左侧CPA处的PCNSL在影像学上酷似三叉神经鞘瘤并伴有相应临床体征。影像学检查显示左侧CPA区有一病变，经活检确诊为弥漫性大B细胞淋巴瘤。鉴于其罕见性，所有CPA区肿瘤的鉴别诊断均应考虑PCNSL。
