摘要 目的 探讨免疫正常人原发性中枢神经系统淋巴瘤(PCNSL)的诊断、治疗方法 及预后因素.方法 回顾性分析本科收治7例经病例证实为PCNSL的临床及影像学资料、治疗方法 .结果 发病到诊断时间2~42(15.6±18.3)周,男5例,年龄30~61(50±11.0)岁.KPS>70分6例.临床表现多为高颅压以及局灶性神经损害症状.MRI为T1-WI稍低、T2-WI高异常信号.CT表现为等密度/高密度肿块,增强扫描病灶呈均匀一致明显强化,周围较明显水肿带.其中3例为多发病灶,5例病灶位于幕上.6例为弥漫大B细胞非何杰淋巴瘤.全脑照射30~50(38±8.7)Gy,局部补照10~20(15±4.9)Gy.生存时间12~30(中位时间20)个月.结论 PCNSL临床表现缺乏特征性,影像学检查表现为幕上深部脑白质单发或多发肿块,诊断依赖于病理,术后放疗较单纯手术生存期长,年龄和一般行为状况是主要预后因素.
