A 28-year-old male presented with a rare case of an aneurysm at the origin of duplication of the middle cerebral artery manifesting as subarachnoid hemorrhage. Preoperative angiography revealed duplication of the right middle cerebral artery and an aneurysm at its origin, which was successfully clipped. He was discharged with no neurological deficits. Congenital factors may be more important in the etiology of aneurysms associated with this anomaly.
一名28岁男性出现罕见病例，大脑中动脉重复起源处的动脉瘤表现为蛛网膜下腔出血。术前血管造影显示右侧大脑中动脉重复且其起源处有动脉瘤，该动脉瘤成功夹闭。患者出院时无神经功能缺损。先天性因素在与这种异常相关的动脉瘤病因中可能更为重要。
