| 摘 要： | 目的探讨大脑后部可逆性脑病综合征(PRES)的影像特征及鉴别诊断。方法回顾分析35例子痫患者影像资料。其中20例有治疗后复查的影像资料,15例有治疗过程中的MRI检查资料。结果 26例CT表现为顶和(或)枕叶片状低密度,且具有可逆性;15例MR表现为T1WI稍低信号,T2WI稍高信号,T2Flair呈高信号,DWI呈等信号,另7例合并脑出血。结论大脑后部可逆性脑病较具有特征性,但需要与其他脑内片状水肿影像表现的疾病进行鉴别。

| Abstract: | Objective To investigate imaging features and differential diagnosis of Posterior reversible encephalopathy syndrome attributed to Hypertension during pregnancy.Methods The imaging findings of 35 patients with eclampsia were analyzed retrospectively(20 cases had images after treatment;15patients had MRI images during treatment).Results CT and MRI images of 26 cases showed patchy low density area in the parietal and occipital lobe which is reversible.15 cases showed slightly low signal intensity on T1WI,slightly high signal intensity on T2WI,high signal intensity on T2Flair and equal signal intensity on DWI.Images of other 7 cases showed combined brain hemorrhage.Conclusion Images of PRES have clear characteristics,but it must be distinguished from other diseases which showed intracephalic pachy edema. |
