摘要 目的总结渗透性髓鞘溶解综合征(ODS)的核磁特点及非典型表现。方法收集2005-03—2013-07我院就诊的8例ODS患者资料,分析其临床及影像特点。8例患者病因各异,其中垂体瘤术后2例,酗酒1例,脑外伤合并尿崩症3例,席汉综合征2例。8例均行T1、T2、Flair序列检查,4例行增强扫描,3例行DWI,2例行MRS,3例行梯度回波(T2*)检查。结果 8例患者核磁扫描发现尾状核受累7例,壳核7例,丘脑4例,颞叶1例,额叶1例,顶叶1例,桥脑6例。增强扫描4例,其中2例可见增强。DWI异常3例,1例(1/3)梯度回波可见桥脑、丘脑对称分布的微出血灶。结论渗透性髓鞘溶解综合征以桥脑基底部、尾状核、豆状核、丘脑为常见好发部位,可累及皮层,可存在微出血病变,DWI序列有助于早期诊断。
