【摘要】：目的:对子痫引起的脑后部可逆性病变(子痫脑病)的影像学表现进行分析,加深对本病的认识。方法:回顾性分析我院2015年3月至2016年3月9例子痫脑病患者的临床表现、CT检查、MRI检查资料。9例行CT检查及磁共振成像(MRI)检查,5例于314天后复查MRI。结果:9例CT平扫为不规则形低密度区;MRI平扫T1WI上低信号,T2WI及T2Fliar呈高信号,扩散加权成像(DWI)病灶呈高信号,弥散表观系数(ADC)图上呈高信号。7例增强扫描均未见强化。3例行磁共振血管成像(MRA)均未发现特殊。1例患者磁共振静脉血管成像(MRV)检查正常。经治疗后5例复查MRI,3例显示病灶完全消失,病灶范围明显缩小者2例。病变主要以双侧顶枕叶为主,其次是额叶和颞叶,基底节区和小脑半球亦有累及。临床出现抽搐9例,头痛7例、视物模糊1例,意识障碍4例。治疗后症状缓解或消失,实验室指标恢复正常。结论:子痫脑病常急性起病,收缩压及舒张压均突然增高。影像学表现非常具有特征性,MRI扩散加权成像对鉴别诊断及早期明确诊断和指导治疗有重要的意义。
[Abstract]:Objective: to analyze the imaging findings of reversible lesions in the posterior part of the brain (eclampsia) caused by eclampsia. Methods: the clinical manifestations of patients with eclampsia from March 2015 to March 9th 2016 were analyzed retrospectively. 9 cases of MRI were examined by CT and Mr imaging (MRI) in 5 cases after 314 days. Results 9 cases of CT showed irregular low density area. Hypointensity T _ 2WI and T _ 2Fliar on MRI plain scan were hyperintense, and diffusion weighted imaging (DWI) showed high signal intensity on T _ 2WI and T _ 2Fliar. Diffusion apparent coefficient (ADCG) showed high signal intensity in 7 cases. No enhancement was found in any of the 7 cases. 3 cases of MRA-MRA were not found in any of the 7 cases. No special cases were found in all of them. The examination was normal. After treatment, MRI was reexamined in 5 cases. In 3 cases, the lesion disappeared completely and the lesion area was obviously reduced in 2 cases. The lesions were mainly bilateral parietal occipital lobe, followed by frontal lobe and temporal lobe, and the basal ganglia and cerebellar hemisphere were also involved. Convulsions occurred in 9 cases. There were 7 cases of headache, 1 case of blurred vision and 4 cases of disturbance of consciousness. The symptoms were relieved or disappeared after treatment, and the laboratory indexes returned to normal. Conclusion: eclampsia encephalopathy often starts acute. Systolic blood pressure and diastolic blood pressure increased suddenly.

【正文快照】： 子痫是产科重症,临床表现以头痛、眼花为主要。子痫引起的脑后部可逆性病变(子痫脑病),病情往往危急,其影像学表现颅内病灶分布具有一定特征性,且在病因及时纠正后病灶可短期内消失。本文对我院经临床及影像确诊的9例子痫脑病的临床及影像学资料的进行分析,旨在加深对该病的认
