Typical Manifestations of Wernicke’s Encephalopathy on Magnetic Resonance Images and Literature Review

目的探讨Wernicke脑病的典型MRI表现。方法结合文献复习,分析13例Wernicke脑病的临床表现与MRI表现。结果 Wernicke脑病典型MRI表现为第三、四脑室旁、中脑导水管周围、乳头体、四叠体、丘脑内侧对称性异常信号,T1WI呈稍低信号,T2WI呈高信号,T2FLAIR呈高信号。结论 Wernicke脑病的MRI表现具有特征性,结合临床,往往能够得出正确诊断。

Objective To study the typical manifestation of the Wernicke＇ s encephalopathy （WE） on magnetic resonance images （MRI）. Methords An analysis was made to the clinical symptoms and MRI manifestation of 13 cases with WE in combination with lit- erature review. Results The typical MRI manifestation of WE included： the abnomlal signals symmetrically surrounding the third and forth ventricle, midbrain aqueduct, mamillary body, quadrigeminal bodies and medial thalamus, the lower signals of T2WI, the high sig- nals of T2WI and the high signals of T2 FLAIR as well. Conclusions The MRI manifestations of WE are of characteristic fcatures, it can lead to a correct diagnosis when combined with clinical symptoms.
