Unilateral oculomotor nerve palsy, often caused by aneurysmal compression, is one of the decisive findings for confirming the site of a ruptured aneurysm. However, arterial compression can also cause unilateral oculomotor nerve palsy. Here, we present the case of a 59-year-old woman with a ruptured right internal carotid-posterior communicating artery aneurysm accompanied by contralateral oculomotor nerve palsy. The nerve was found to be compressed by the posterior cerebral artery and was isolated from the ruptured aneurysm. When confirming a ruptured aneurysm based on the evidence of unilateral oculomotor palsy, the arteries surrounding the nerve must be thoroughly assessed.
单侧动眼神经麻痹，常由动脉瘤压迫引起，是确定破裂动脉瘤部位的决定性发现之一。然而，动脉压迫也可导致单侧动眼神经麻痹。在此，我们报告了一例 59 岁女性，右侧颈内动脉-后交通动脉瘤破裂，伴有对侧动眼神经麻痹。发现神经被大脑后动脉压迫，与破裂的动脉瘤分离。当根据单侧动眼神经麻痹的证据确定破裂的动脉瘤时，必须彻底评估神经周围的动脉。
