目的：分析脑后部可逆性脑病综合征的临床特征及MRI表现。方法：2012年12月至2014年2月在我院治疗的6例PRES患者，分析其临床及MRI表现特点。6例患者中，女性5例，男性1例，均行MR T1WI、T2WI、水抑制序列（FLAIR）；5例患者行MR静脉成像（MRV）；1例患者行MR扩散加权成像（DWI）。结果：本组6例患者中，4例继发于妊娠高血压，慢性肾炎伴肾功能不全透析1例，系统性红斑狼疮1例，其中癫痫发作3例。6例均有头痛头晕，意识障碍2例，轻偏瘫1例。M R I表现：双侧顶叶、枕叶（6例）、基底节区（2例）、额叶（1例）、颞叶（1例）多发异常信号。病灶主要位于双侧顶枕叶皮质下白质内，有2例患者皮层亦受累，在T1W I病灶表现为等或略低信号，T2WI及FLAIR呈高信号。FLAIR序列显示病灶最佳。6例患者经治疗后随访MRI显示所有患者病灶范围、数目逐渐变小、减少或消失。结论：PRES临床主要表现包括头痛头晕、意识障碍或癫痫发作。MRI表现为T1WI等或略低信号、T2WI及FLAIW高信号。病变为血管源性水肿。及早诊断及早治疗十分重要。
目的：分析腦後部可逆性腦病綜閤徵的臨床特徵及MRI錶現。方法：2012年12月至2014年2月在我院治療的6例PRES患者，分析其臨床及MRI錶現特點。6例患者中，女性5例，男性1例，均行MR T1WI、T2WI、水抑製序列（FLAIR）；5例患者行MR靜脈成像（MRV）；1例患者行MR擴散加權成像（DWI）。結果：本組6例患者中，4例繼髮于妊娠高血壓，慢性腎炎伴腎功能不全透析1例，繫統性紅斑狼瘡1例，其中癲癇髮作3例。6例均有頭痛頭暈，意識障礙2例，輕偏癱1例。M R I錶現：雙側頂葉、枕葉（6例）、基底節區（2例）、額葉（1例）、顳葉（1例）多髮異常信號。病竈主要位于雙側頂枕葉皮質下白質內，有2例患者皮層亦受纍，在T1W I病竈錶現為等或略低信號，T2WI及FLAIR呈高信號。FLAIR序列顯示病竈最佳。6例患者經治療後隨訪MRI顯示所有患者病竈範圍、數目逐漸變小、減少或消失。結論：PRES臨床主要錶現包括頭痛頭暈、意識障礙或癲癇髮作。MRI錶現為T1WI等或略低信號、T2WI及FLAIW高信號。病變為血管源性水腫。及早診斷及早治療十分重要。

Objective:To analyzed clinical features and MRI performance of posterior reversible encephalopathy syndrome.Methods:Collect all prtients with PERS treated in our hospital from 2006 to 2011 to analysis the clinical and MRI presentation of PRES. This teaminclude 5 women and only one man. All of them had MR imaging(T1WI、T2WI、FLAIR),three cases had MRV, and one cases had MR imaging DWI.Resulte:In this team,four cases caught PRES after pregnancy-inducedhy pretension. One case got PRES after systemic lupus erythematosus,three of them got seizures, all of them got headaches, two of them got disturbance of consciousness, and one of them had hemiplegia.MRI demonstrated multiple lesions located in bilateral parieto-occipital(6 cases),bilateral basal ganglia(2 cases),and bilateral frontal lobes(1 case).The lesions were prominent within white matter, some of them involved gray matter(2 cases).Lesions appeared as hyperintense signals on FLAIR and T2-weighted images,isointense or mildly hyperintense signals on T1-weighted images.FLAIR has advantages to display lesion in PRES. All of them received treatment had MR imaging show that lesions of PRES had become smallse or even vanished. Conclusion:PRES clinical represents mainly include headaches,seizures or disturbance of consciousness. MRI showed T1WI isointense or mild hypointense, T2WI and FLAIR hyperintense. Lesions are vasogenicedema. Early diagnosis and early treatment is very important.
