摘要
目的回顾分析19例原发性中枢神经系统淋巴瘤的资料,旨在探讨脑淋巴瘤的表现特点,以提高对本病的认识。方法 19例患者均行常规MRI平扫及增强检查,分析病灶的MRI特点。结果 19例患者共发现病灶24处,单发病灶15例,多发病灶4例。其中病灶位于额叶4例,颞叶6例,基底节7例,胼胝体4例,顶叶1例,小脑2例。11例病灶主要分布于皮层及皮层下,13例病灶分布于深部脑白质。肿瘤多为类圆形团块状,其中位于胼胝体者可呈蝴蝶状。19例病灶信号均匀,5例瘤内可见小斑点状长T1长T2信号。增强后21例肿瘤明显均匀增强,3例为环状强化。结论 MRI检查可为原发性中枢神经系统淋巴瘤的诊断提供极其重要的依据,为指导临床治疗提供帮助。
Objective The study was to assess the performance characteristics of brain lymphoma,and raise the awareness of the disease by retrospectively analyzing 19 cases of primary central nervous system lymphoma.Method 19 patients underwent sagittal,axial and coronal MRI scan and enhanced examination.Results In 19 patients（15 of them were solitary,4 were multiple）,total 24 lesions were found.The lesions in the frontal lobe in 4 cases,temporal lobe in 6 cases basal ganglia in 7 cases,corpus callosum in 4 cases,parietal lobe in 1 case,cerebellum in 2 cases.Lesions in 11 cases mainly distributed in the cortex and subcortical,13 cases were located in deep white matter.Almost all lesions appeared as quasi-circular masses,which in the corpus callosum maybe look like ＂butterfly sign＂.In 19 cases the lesions signal is uniformity,in 5 cases small spots with long T1,T2 signal were seen.Homogeneous enhancement in 21cases,ring enhancement in 3 cases.Conclusion MRI examination for primary central nervous system lymphoma diagnosis is extremely important,and very helpful for clinical treatment.
