Abstract

Posterior alien hand syndrome is a new addition to a poorly understood group of movement disorders. Historically, anatomical lesions causing uncontrolled limb movement and a feeling of foreignness were found to be located in the corpus callosum or frontal lobe. Recent case reports, however, demonstrate the typical symptoms of alien hand syndrome with lesions located in the parietal/occipital lobes. Disturbance of normal function in these regions tends to produce less complex motor activity, such as hand levitation, along with a sensory component characterized by feeling of estrangement. We discuss a patient who presented with unusual symptoms following an outpatient procedure and was found to have posterior alien hand syndrome.

摘要

后部异己手综合征是一组了解甚少的运动障碍中的新成员。从历史上看,导致肢体不受控制运动和异物感的解剖学病变被发现位于胼胝体或额叶。然而,最近的病例报告显示,异己手综合征的典型症状出现在顶叶/枕叶有病变的患者身上。这些区域正常功能的紊乱往往会产生不太复杂的运动活动,如手部悬浮,同时伴有以陌生感为特征的感觉成分。我们讨论了一名在门诊手术后出现异常症状的患者,该患者被诊断为后部异己手综合征。
