[摘 要] 目的：分析颅内原发性淋巴瘤 CT和 MRI的影像学表现,旨在提高对该病的诊断与鉴别诊断率。方法：回顾性分析12例经病理证实的颅内原发性淋巴瘤的CT与MRI表现。结果：单发8例,多发4例,共计15个病灶,病理类型均为B细胞型非霍奇金淋巴瘤。CT表现等密度或稍高密度实质性肿块,无钙化,瘤周水肿相对较轻,占位效应轻,增强后瘤体呈均匀性中度强化,无囊变及环形强化。MRI显示为长T1、长T2信号,增强后病灶明显强化。结论:脑内原发淋巴瘤少见,影像学表现与颅内其他肿瘤互相重叠,CT和MRI平扫和增强扫描的应用有助于脑内淋巴瘤的诊断和鉴别诊断。[关键词] 脑恶性淋巴瘤；体层摄影术；X线计算机；磁共振成像
