Extranodal natural killer (NK)/T cell lymphomas, nasal type, are aggressive, non-Hodgkin lymphomas. Extranodal NK/T cell lymphomas, nasal type, involving the central nervous system (CNS) are rare; therefore, delayed diagnosis easily occurs and is associated with a poor prognosis. Early diagnosis and patented systemic chemotherapy are necessary.
We present a case of 34-year-old male with facial numbness and diplopia. He was diagnosed with extranodal NK/T cell lymphoma, nasal type, involving the CNS. The tumor, located in the right middle fossa, was subtotally removed, and 3 cycles of systemic chemotherapy were given. He later died of severe neutropenia and infection.
NK/T cell lymphomas should be considered to be a potential cause of facial numbness and diplopia. A L-asparaginase-based regimen resulted in reasonable tumor suppression, but adverse effects, including fatal neutropenia, should be carefully considered.
结外自然杀伤（NK）/T细胞淋巴瘤，鼻型，是侵袭性非霍奇金淋巴瘤。结外NK/T细胞淋巴瘤，鼻型，累及中枢神经系统（CNS）很罕见；因此，容易出现诊断延迟且预后较差。早期诊断和有效的全身化疗很有必要。
我们报告一例34岁男性，有面部麻木和复视症状。他被诊断为结外NK/T细胞淋巴瘤，鼻型，累及中枢神经系统。肿瘤位于右侧中颅窝，行次全切除，并给予3个周期的全身化疗。他后来死于严重中性粒细胞减少和感染。
NK/T细胞淋巴瘤应被视为面部麻木和复视的潜在病因。基于左旋门冬酰胺酶的方案可实现合理的肿瘤抑制，但包括致命性中性粒细胞减少在内的不良反应应予以谨慎考虑。
