目的探讨子痫性脑病的MRI特 点。方法 分析9例子痫性脑病患者的MRI 资料。9例行MRI检查，经临床治疗后行 MRI复查。结果 9例MRI显示双侧大脑半球 后部白质区为主的对称性斑片状影，病灶 均呈两侧大致对称性分布，多数病灶位于 顶枕叶皮层下白质区、颞叶及小脑半球； 病灶T1WI主要呈低、稍低信号、T2WI呈稍 高信号、FLAIR呈较高信号、DWI呈稍高信 号，MRA和MRV均未见明显异常；经对症治 疗后神经系统症状完全消失，复查MRI显 示仅1例基底节区尚残余少许病灶，其余 病灶均已消失。结论 子痫性脑病的MRI表 现具有一定特征性，提高对该病的临床及 MRI特点的认识，对于该病早期诊断、及 时治疗和疗效评估具有非常重要的意义。

Objective To investigate the MRI features of eclamptic encephalopathy. Methods Analyze the MRI performance of 9 cases of eclamptic encephalopathy. A total of 9 cases underwent MRI examination, all cases had been follow-up after clinical treatment. Results All the 9 cases of MRI showed the symmetrical patches of the white matter in the posterior portion of the bilateral cerebral hemisphere, the lesions were generally distributed on both sides, most of the lesions located in the top occipital subcortical white matter area, temporal lobe and cerebellum, the lesion on T1WI was low or slightly lower signal, and was slightly higher signal on T2WI, higher signal on FLAIR, slightly higher signal on DWI, and MRA and MRV showed no obvious abnormality. After treatment, the neurological symptoms completely disappeared, and the MRI revealed that only one of the base regions remained a few lesions, and the other lesions had disappeared. Conclusion The MRI findings of eclampsia encephalopathy has certain characteristic. Improving the understanding of clinical and MRI features of eclampsia is very important for early diagnosis, timely treatment and evaluation of the disease.
