摘要
目的:分析总结慢性酒精中毒性脑病患者的头颅MRI表现。方法:回顾性分析本院临床确诊的17例慢性酒精中毒性脑病患者的临床及其影像学资料。结果:17例患者均有明确长期嗜酒史,且全部行头颅MRI检查,其中1例(5.9%)表现为典型的Marchiafava-Bignami脑病;2例(11.8%)表现为Wernicke脑病;3例(17.6%)主要表现为大脑及小脑蚓部萎缩;3例(17.6%)主要表现为大脑萎缩;4例(23.5%)仅表现为大脑半球深部、基底节区、脑桥存在非对称性小片状长T1、长T2异常信号灶,表现为脑萎缩的6例患者也同时存在此种表现;4例(23.5%)无明确MRI阳性发现。结论:MRI在慢性酒精性脑病诊疗过程具有积极作用,可帮助临床及时正确诊断,避免不可逆性脑损伤的出现。
Objective： This study was undertaken to analyze findings on MR imaging of patients with chronic alcoholic toxic encephalopathy. Methods： MR brain imaging findings, clinical histories and presentations of 17 patients （1 female, 16 males） were reviewed retrospectively with chronic alcoholic toxic encephalopathy diagnosed between 2003 and 2008. Results：All of the patients had a history of alcohol abuse. According to MR findings, 1 case （5. 9%） appeared as typical Marchiafava-Bignami disease, 2 （11.8%） as Wernicke encephalopathy, 3 （ 17. 6%） as brain and cerebellar vermis atrophy and 3 （17.6%） as only brain atrophy,4 cases （23.5%） showed asymmetric lesions in the deep white matter of cerebral hemisphere,basal ganglia area and pons,which were also found in all of the 6 cases with cerebellum or brain atrophy. 4 （23.5%） of the patients were normal. Conclusion： Our study confirms the usefulness of MRI in reaching diagnosis of chronic alcoholic toxic encephalopathy to avoid further damage to the brain tissue.
