Aneurysms of the penetrating branches of the middle cerebral artery are rare. Previous reports have concentrated on aneurysms that arise from the distal lenticulostriate artery where the natural history is unclear. Here, we report a case of a ruptured aneurysm located at the insular penetrating branch of the right middle cerebral artery, which was associated with an external capsular haematoma. The aneurysm persisted as shown by angiography at one month and the patient refused surgical treatment at that stage. Follow-up angiography two years later showed resolution of the aneurysm. The aetiologies and treatment options are reviewed.
大脑中动脉穿支动脉瘤较为罕见。既往报道主要集中于起源于豆纹动脉远端的动脉瘤，其自然病程尚不清楚。在此，我们报告一例位于右侧大脑中动脉岛叶穿支的破裂动脉瘤，该动脉瘤伴有外囊血肿。动脉瘤在1个月时血管造影显示依然存在，此时患者拒绝手术治疗。两年后的随访血管造影显示动脉瘤消失。本文对其病因及治疗选择进行了综述。
