Alien hand syndrome (AHS) is characterized by involuntary and autonomous activity of the affected limbs, and consists of the frontal, callosal and posterior AHS variants. The callosal subtype, resulting from damage to the corpus callosum, frequently features intermanual conflict. However, infarction of the corpus callosum is rare due to abundant blood supply. The present study reported a case of AHS (callosal subtype, in the right hand) caused by callosal infarction. Infarction of the left corpus callosum was confirmed with magnetic resonance imaging. In addition, magnetic resonance angiography and digital subtraction angiography examinations revealed multiple lesions in the feeding arteries. Subsequent to antiplatelet therapy for 2 weeks following admission, the patient gradually recovered. Furthermore, the current study reviewed 31 previously reported cases of AHS following callosal infarction in the literature.
异己手综合征（AHS）的特征是受影响肢体的不自主和自主活动，包括额叶型、胼胝体型和后型AHS变体。胼胝体亚型由胼胝体损伤引起，常表现为双手冲突。然而，由于血供丰富，胼胝体梗死很少见。本研究报告了一例由胼胝体梗死引起的AHS（胼胝体亚型，右手）病例。磁共振成像证实左侧胼胝体梗死。此外，磁共振血管造影和数字减影血管造影检查显示供血动脉有多处病变。入院后进行2周的抗血小板治疗后，患者逐渐康复。此外，本研究还回顾了文献中先前报道的31例胼胝体梗死后AHS病例。
