摘　　要：目的:分析原发性中枢神经系统淋巴瘤(PCNSL)计算机断层扫描(CT)、磁共振成像(MRI)表现及临床病理特征。方法:回顾2017年12月至2018年12月岳阳市第二人民医院收治的60例PCNSL患者的临床资料,对其CT、MRI表现及临床病理特征进行分析。结果:PCNSL多因颅内高压症状起病,同时伴有共济失调症;CT表现为大部分病灶周围均存在较为明显的水肿带;MRI表现为等或稍长T2信号、等或稍长T1信号,增强扫描后呈均匀强化,有握拳征、缺口征等特征性表现;病理特征上B细胞型淋巴瘤51例、T细胞型淋巴瘤9例。结论:PCNSL临床表现特殊性不明显,但免疫组化和影像学表现具有特征性,同时临床需将其与胶质瘤、脑转移瘤及脑膜瘤等区别。Objective To analyze the computerized tomography(CT),Magnetic resonance imaging(MRI)performance and clinicopathological characteristics of primary central nervous system lymphoma(PCNSL).Methods The clinical data of 60 PCNSL patients admitted to Yueyang Second People's Hospital from December 2017 to December 2018 were reviewed,and their CT,MRI performance and clinical pathological characteristics were analyzed.Results PCNSL is usually due to symptoms of intracranial hypertension,accompanied by ataxia;CT shows that there are more obvious edema bands around most of the lesions;MRI shows equal or slightly longer T2 signal,equal or slightly longer T1 The signal was uniformly enhanced after enhanced scanning,with characteristic manifestations such as fist-fist sign and gap sign;51 cases of B-cell lymphoma and 9 cases of T-cell lymphoma were pathological features.Conclusion The specificity of the clinical manifestations of PCNSL is not obvious,but the immunohistochemical and imaging manifestations are characteristic.At the same time,it needs to be clinically distinguished from gliomas,brain metastases,and meningiomas.
