A 60-year-old woman presented with a rare unruptured aneurysm of duplication of the middle cerebral artery (DMCA) identified at examination for headache. Preoperative cerebral angiography revealed the DMCA and a small aneurysm at its origin. Surgical clipping was performed successfully via the trans-sylvian approach. DMCA aneurysms have a tendency to bleed even if small, but the anatomical configuration causes some technical difficulties.
一名60岁女性因头痛检查时发现罕见的大脑中动脉重复畸形未破裂动脉瘤（DMCA）。术前脑血管造影显示了DMCA及其起始处的一个小动脉瘤。通过经侧裂入路成功进行了手术夹闭。DMCA动脉瘤即使很小也有出血倾向，但解剖结构导致了一些技术难题。
