Some anterior choroidal artery (AChA) infarctions in the posterior limbs of the internal capsule (plIC) have been reported to cause aphasia, typically with apparent paralysis. We herein report an 84-year-old woman with AChA infarction. Although her dysarthria remained mild with no apparent paralysis, we overlooked progression to branch atheromatous disease-related infarct with exacerbation of her anomia, which delayed the initiation of more intense therapy. Even in AChA infarction, especially when the lesion is located mainly in the anterior part of the plIC, as in our case, it is possible to encounter progressive stroke predominantly with aphasia.
一些发生在内囊后肢（plIC）前部的脉络膜前动脉（AChA）梗死已被报道可引起失语症，通常伴有明显的瘫痪。我们在此报告一例 AChA 梗死的 84 岁女性患者。尽管她的构音障碍仍然轻微，没有明显的瘫痪，但我们忽略了进展为分支粥样硬化性疾病相关梗死的情况，导致其命名障碍加重，从而延迟了更强化治疗的开始。即使在 AChA 梗死中，特别是当病变主要位于 plIC 的前部时，如我们的病例，也可能会遇到主要表现为失语症的进行性卒中。
