Abstract

Posterior inferior cerebellar artery (PICA) aneurysm is relatively rare. We report on a 74-year-old woman presenting with dizziness and right-side tilted gait caused by a right-side distal PICA aneurysm, which mimicked a right lateral medullary infarction. A neurological examination showed right-side limb ataxia and left-beating torsional nystagmus, similar to a right lateral medullary infarction. Magnetic resonance imaging revealed a distal PICA aneurysm in the right-side middle cerebellar peduncle region.

摘要

小脑后下动脉（PICA）动脉瘤相对少见。我们报告一例74岁女性，因右侧小脑后下动脉远端动脉瘤出现头晕及向右侧倾斜步态，该表现酷似右侧延髓外侧梗死。神经系统检查显示右侧肢体共济失调及向左跳动的扭转性眼球震颤，与右侧延髓外侧梗死相似。磁共振成像显示右侧小脑脚中部区域有一个小脑后下动脉远端动脉瘤。
