异手综合症（AHS）是一种不自主的不受控制的手臂运动，与肢体本身有疏远感。AHS最初被用于描述胼胝体前部病变患者的半球间断开现象，但在未累及胼胝体的大脑后部病变患者中也发现了这种现象，例如顶叶梗死或皮质基底变性。后异手综合征较少见，表现为无目的行为，如抬起手臂或扭动手指。我们报告一个80岁的妇女与后AHS的右手优势。MRI显示中枢前回和中枢后回萎缩，但胼胝体未受累。我们讨论了后侧AHS的病因及其与前侧AHS的区别。
The alien hand syndrome (AHS) is involuntary uncontrolled movement of an arm with a sense of estrangement from the limb itself. AHS was initially used to describe interhemispheric disconnection phenomena in patients with lesions in the anterior corpus callosum, but it has been found in patients with posterior cerebral lesions without involvement of the corpus callosum, for example parietal infarcts or corticobasal degeneration. The posterior alien hand syndrome is less frequent and presents with nonpurposive behaviour like lifting the arm or writhing fingers. We report an 80-year-old woman with a posterior AHS of the dominant right hand. MRI showed atrophy of the pre- and postcentral gyri without involvement of the corpus callosum. We discuss the aetiology of the posterior AHS and the differences from the anterior varieties.
