Most intracranial aneurysms (approximately 90%) arise in the carotid circulation. 30-35% of aneurysms arise from the anterior communicating artery, 30-35% from the posterior communicating artery origin, 20% from the middle cerebral artery bifurcation, 5% from the basilar artery bifurcation or tip and the remaining 1-5% arise from other posterior fossa vessels. Saccular aneurysms larger than 2.5cm are called giant aneurysms.
Although MR angiography appears promising, catheter angiography is usually required for the definitive diagnosis and preoperative delineation of intracranial aneurysms.
