摘　　要：目的探讨MRI诊断不典型原发性中枢神经系统淋巴瘤的价值。方法选取2015年1月至2019年2月医院收治的31例不典型原发性中枢神经系统淋巴瘤患者,回顾性分析其病理结果,并采取MRI扫描作为对照。结果31例患者中,29例诊断为囊性变化,患者T 1WI显示单房低信号影,且实质信号不均匀,患者自身肿瘤部位多发生水肿,肿瘤在检测中呈高信号;2例诊断为囊变合并出血,患者T 1WI、T 2WI在囊实性混杂信号区显示为高信号。脑内多发结节病灶1例,增强扫描过程中呈现为均匀性强化。31例患者,经MRI确诊30例,诊断准确率为96.77%。结论不典型原发性中枢神经系统淋巴瘤诊断难度较高,需要结合MRI影像学特点、临床表现等进行诊断,MRI对提高不典型原发性中枢神经系统淋巴瘤的诊断效果有重要作用。Objective To investigate the accuracy and value of MRI in the diagnosis of atypical primary central nervous lymphoma.Methods 31 patients with atypical primary central nervous lymphoma admitted to our hospital from January 2015 to February 2019 were randomly selected for study.The pathological results of 31 patients were analyzed retrospectively and MRI scanning was taken as control.Results Of the 31 patients,29 were cystic changes.Cystic changes had low signal intensity in single room on T1WI,and the parenchymal signals of patients were not uniform.Edema often occured in tumor sites of 29 patients,and tumors showed high signal intensity in detection.2 patients were diagnosed as cystic degeneration complicated with hemorrhage.The diagnosis showed that T1WI showed high signal in cystic-solid mixed signal area.In addition,two patients also showed high signal in T2WI also showed cystic-solid mixed signal area.There was 1 case of multiple nodular lesions in the brain,which showed homogeneous enhancement during the enhanced scanning.Among the 31 patients,30 were confirmed by MRI,with a diagnostic accuracy of 96.77%.Conclusion The diagnosis of atypical primary central nervous lymphoma is very difficult,which needs to be combined with MRI imaging features and clinical manifestations.MRI imaging plays an important role in improving the diagnosis effect of atypical primary central nervous lymphoma,and is worthy of wide promotion and clinical application.
