摘要 目的探讨渗透性髓鞘溶解综合征MRI影像学表现,提高该病的认识及诊断水平。方法回顾性分析6例我院临床证实渗透性髓鞘溶解综合征患者的MRI平扫及扩散加权成像(DWI)表现。结果 6例患者中5例均有桥脑中央髓鞘溶解征(MRI平扫桥脑见类圆形及三角形长T1、长T2信号、3例DWI呈明显高信号、2例呈等或稍高信号);2例合并桥脑外髓鞘溶解征(双侧尾状核、豆状核、丘脑见对称性片状长T1、长T2信号、T2FLAIR稍高信号、DWI等及稍高信号);1例仅表现桥脑外髓鞘溶解征(双侧尾状核、豆状核见对称性长T1、长T2信号、DWI明显高信号)。结论渗透性髓鞘溶解综合征(ODS)以桥脑基底部、尾状核、豆状核及丘脑为好发部位,采用MRI平扫及DWI成像结合临床特征,可做出较为明确诊断。
