【摘要】 目的 分析慢性酒精中毒性胼胝体变性的MRI征象。方法 4例慢性酒精中毒性胼胝体变性病例均行常规颅脑MRI检查，其中2例行MRI增强扫描。结果 4例胼胝体均有不同程度萎缩，均呈不均匀长T 1 、长T 2 信号改变;2例强化扫描均未见明显异常对比强化。结论 胼胝体变性是慢性酒精中毒的并发症之一，其主要表现为长T 1 、长T 2 异常信号;MRI是诊断胼胝体变性的有效方法。

    【Abstract】 Objective To analyze the MRI findings of callosum degeneration caused by Marchiafava-Bignaˉmi disease.Methods Perform routine MRI on4cases of callosum degeneration caused byMarchiafava-Bignami disˉease.2of the4cases were performed enhanced MRI scan.Results All the callosums in the4cases were in some deˉgree atrophied.The signal of callosums in all the cases reveal long T1and T2.The signal of the2enhanced MRI scan reveal no abnormal contrast enhancement.Conclusion Callosum degeneration is one of the complications of Marchiˉafava-Bignami Disease.The main features of callosum degeneration on MRI are abnormal signals of long T1and long T2singal.MRI is an effective way to diagnose callosum degeneration. ......
