颅脑MRI检查对Wernicke脑病的诊断价值

目的 探讨颅脑MRI检查对Wemicke脑病(WE)的诊断价值.方法 回顾性分析8例WE患者的临床资料及MRI检查结果.结果 8例WE患者MRI示脑部T2 WI、Flair成像及弥散加权成像(DWI)有对称性异常高信号影,其中出现在丘脑内侧6例、中脑导水管周围灰质4例、第三脑室周围灰质3例、乳头体2例及壳核、视交叉、小脑上蚓部、皮质下白质各1例;2例有增强效应.2例发病早期T2 WI、Flair无异常信号影,DWI示丘脑内侧对称性异常高信号影.结论 MRI对WE具有诊断价值,DWI对WE的早期诊断价值更高.

Value of craniacerebral MRI on diagnosis of Wernicke's encephalopthy

Objective To investigate the value of craniacerebral MRI on the diagnosis of Wernicke's encephalopathy(WE).Methods The clinical data and MRI scope-consequence of 8 patients with WE were analyzed retrospectively.Results MRI of all WE patients showed symmetrical high signals on the brain T2WI,Flair and diffusion weighted imaging(DWI),6 cases of them in the medial thalamus,4 cases in surrounding the aqueduct,3 cases in the third ventricle gray matter,2 cases in the mamillary bodies,1 case in the putamen,1 case in the optic chiasm,1 case in the superior cerebella vermis and 1 case in the subcortical white matter;2 cases had reinforcement effect.2 cases showed no abnormal signals on T2WI and Flair early,but showed high signal symmetrically in the medial thalamus on DWI imaging.Conclusions MRI is of value to the diagnosis of WE.DWI is more helpful for the early diagnosis of WE.
