Mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinico-radiological syndrome with a very particular clinical course. Three patients with MERS were evaluated by various sequences of magnetic resonance imaging with diffusion tensor imaging. Initial diffusion-weighted imaging showed reduction in the apparent diffusion coefficient values in the lesions, which completely resolved with the elimination of symptoms. However, diffusion anisotropy of the lesions showed no remarkable abnormalities in the early or delayed phases. These results may indicate that white matter architecture is preserved in both early and delayed phases in MERS.
伴可逆性胼胝体压部病变的轻度脑炎/脑病（MERS）是一种临床病程非常特殊的临床-放射学综合征。对3例MERS患者进行了多种磁共振成像序列检查，包括扩散张量成像。最初的扩散加权成像显示病变部位表观扩散系数值降低，随着症状消除，病变完全消失。然而，病变的扩散各向异性在早期和延迟期均未显示明显异常。这些结果可能表明，MERS在早期和延迟期白质结构均得以保留。
