Cerebral aneurysm

A cerebral or brain aneurysm is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. A common location of cerebral aneurysms is on the arteries at the base of the brain, known as the Circle of Willis. Aneurysms may result from congenital defects, preexisting conditions such as high blood pressure and atherosclerosis (the buildup of fatty deposits in the arteries), or head trauma. Cerebral aneurysms occur more commonly in adults than in children and are slightly more common in women than in men, but they may occur at any age.
