目的 探究酒精性脑病引发的胼 胝体变性的影像学特征。方法 采用回顾 性分析法，对我院2009年-2016年7月收治 的6例胼胝体患者进行分析，每例患者均 行影像检查，并具有完整的影像资料。结 果 其中4例急性患者在CT扫描中胼胝体体 积增大，膝部最为显著，边界不清晰模糊 状，在MRI扫描表现较高信号和高信号； 1例亚急性患者CT中表现为胼胝体发胀程 度较低，边界清晰，病灶变化显示中心层 状明显，在MRI扫描表现较高信号和高信 号；1例慢性型患者体积缩小，体部最显 著，膝部甚至出现坏死，在MRI中表现为 低信号或较低信号。结论 CT和MRI对胼胝 体变性能够直观明了表现病理性改变，其 中MRI全方位成像对诊断更加有利，在临 床诊断上具有重要的意义和价值。

Objective To investigate the image features of corpus callosum degeneration caused by alcohol encephalopathy. Methods Six cases with callosum in our hospital from 2009 to Jan 2016 were selected. They were all given imaging examination and had complete information. Results After CT scan, 4 cases showed volume increase, more significant in knee, unclear border and showed higher signal and high signal in MRI scan. One case subacute in CT scan showed lighter callosum swell, clear border and showed high signal and high signal in MRI scan. One case chronic type volume reduced, more obvious in body, necrosis occurred in knee and showed low signal and low signal in MRI scan. Conclusion CT and MRI can clearly show pathological changes of callosum degeneration. MRI is more favourable to omnibearing imaging and is significant in clinic.
