[Anterior choroidal artery territory infarction with transcortical sensory aphasia after a neck clipping of left internal carotid artery aneurysms: a case report].

ABSTRACT

Anterior choroidal artery (Ach A) syndrome is widely known to be composed of a triad of hemiparesis, hemisensory loss and homonymous hemianopia. The authors report a case of Ach A-territory infarction after a direct operation for internal carotid artery aneurysms, which presented transcortical sensory aphasia in association with the characteristic triad. The literature and several previously reported cases with dominant and nondominant cerebral hemisphere signs in AcH A infarction are reviewed. The danger of Ach A occlusion and the importance of preserving it during aneurysm surgery are emphasized.
