[Abstract] Objective: To investigate the clinical and MRI characteristics of Wernicke encephalopathy after abdominal operation, in order to improve the understanding and diagnostic level of it.Materials and Methods: Retrospectively analyzed the collected clinical and imaging data of four nonalcoholic Wernicke encephalopathy patients after abdominal operation and reviewed the reference literature.Results: Two of the four patients were lethargy, one patient showed spiritual apathy, another one patient performed as listlessness and lacking language and movement. All of the four patients were underwent MR imaging which showed that the symmetric lesions located in the medial thalamus, periventricular region of the third ventricle and the periaqueductal grey matter. Their signals were symmetric slight hyperintensity on T2-weighted images, fluid-attenuated inversion recovery (FLAIR) images and hypointensity on T1- weighted images. Some lesions also showed slight hyperintensity or hyperintensity in DWI images. One patient was performed contrast enhanced scan, but the lesions were not obviously enhanced.Conclusions: The MR signals of nonalcoholic Wernicke encephalopathy had certain specificity, and the clinical manifestation combined with brain MRI examination will be helpful to diagnose of it.
