title: Treatment of unruptured aneurysm of duplication of the middle cerebral artery--case report.
abstract: 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.
