系统性红斑狼疮合并脑后部可逆性脑病综合症的MRI表现

MRI Finding of systemic lupus erythematosus with posterior reversible encephalopathy syndrome

目的探讨系统性红斑狼疮合并脑后部可逆性脑病综合症(PRES)的MRI表现,以提高对该病的认识。方法回顾性分析3例PRES的MRI临床资料和MRI表现并文献复习。结果 MRI显示PRES以顶枕叶白质为主的片状对称性长T1长T2信号、FLAIR高信号病变,部分累及皮层,颞叶后部、额叶也可同时受累。结论 PRES的MRI表现具有鲜明的特征性,结合病史和MRI特征可以早期诊断。

Objective To explore MRI characters of systemic lupus erythematosus with posterior reversible encephalopathy syndrome（PRES）,so as to increase uncler standing.Methods The clinic data and MRI imaging of 3 cases with PRLS were retrospectively analyzed and related reports were reviewed.Results MRI revealed symmetrical multiple patchylike lesions presented hypointense on T1WI,hyperintense on T2WI,and located predominantly in the occipital lobe,some of them involved gray matter.They can provide useful imformation in the bilateral temporal lobes and frontal lobe.Conclusion MRI manifestations of PRES had distinctive characteristic and can be diagnosed on the basis of clinical and MRI feateres in the early stage.
