A partial syndrome of hemisphere disconnection was observed in a 63 year-old woman, following an anterior and middle corpus callosum infarct on MRI. Notably, we found left ideomotor apraxia, diagonistic apraxia, left-year extinction on dichotic listening, but no left-hand anomia nor left visual field anomia. A left tactile extinction in dichaptic condition is interpreted as resultant of a dysregulation of the attentional balance between the two hemispheres. This detailed neuropsychological study permits a correlation between the callosal syndrome and the lesion. We suggest that an occlusion of the anterior callosal artery could explain this limited ischemia.
一名63岁女性在MRI显示胼胝体前部和中部梗死之后，出现了部分大脑半球分离综合征。值得注意的是，我们发现患者存在左侧观念运动性失用、诊断性失用、双耳分听时左侧听觉消退，但没有左手命名性失语或左侧视野失读症。双侧同时触觉刺激时出现左侧触觉消退，这被解释为两个半球之间注意力平衡失调的结果。这项详细的神经心理学研究使胼胝体综合征与病变之间建立了关联。我们认为胼胝体前动脉闭塞可以解释这种局限性缺血。
