An 81 year old right handed woman developed a left alien hand syndrome characterised by involuntary movements of choking and hitting the face, neck, and shoulder. The patient showed multiple disorders of primary sensation, sensory processing, hemispatial attention, and visual association, as well as a combination of sensory, optic, and cerebellar ataxia (triple ataxia) of the left arm in the absence of motor neglect or hemiparesis. Imaging studies disclosed subacute infarction in the right thalamus, hippocampus, inferior temporal lobes, splenium of corpus callosum, and occipital lobe due to right posterior cerebral artery occlusion. This rare syndrome should be considered as a "sensory" or "posterior" form of the alien hand syndrome, to be distinguished from the "motor" or "anterior" form described more commonly.
一名81岁的右利手女性患上了左侧异己手综合征，其特征为出现不自主的掐扼动作以及击打面部、颈部和肩部。该患者表现出多种原发性感觉、感觉加工、半侧空间注意和视觉关联障碍，以及左臂的感觉性、视性和小脑性共济失调（三联征共济失调），且不存在运动忽视或偏瘫。影像学研究显示，由于右侧大脑后动脉闭塞，右侧丘脑、海马体、颞下回、胼胝体压部和枕叶出现亚急性梗死。这种罕见综合征应被视为异己手综合征的“感觉性”或“后部”形式，以区别于更常见的“运动性”或“前部”形式。
