====== Complex middle cerebral artery aneurysm ====== Complex [[middle cerebral artery aneurysm]]s include aneurysms that are sizeable (large or giant), broad-necked, fusiform, dissecting or serpentine. ===== Clinical features ===== They may present with [[intracranial hemorrhage]], [[mass effect]]s, [[epilepsy]] or [[cerebral ischemia]]; in addition, the aneurysm may be incidentally discovered. ===== Treatment ===== see [[Complex middle cerebral artery aneurysm treatment]]. ===== Outcome ===== A high mortality rate of 65–85 % within 2 years (because of rupture or re-rupture) has been reported ((Choi IS, David C. Giant intracranial aneurysms: development, clinical presentation and treatment. Eur J Radiol. 2003;46:178–194. doi: 10.1016/S0720-048X(03)00090-1.)) ((Drake CG, Peerless SJ.
