Cerebral aneurysm



	An aneurysm is a sac-like protrusion of an artery caused by a weakened area within the vessel wall. If a cerebral (brain) aneurysm ruptures, the escaping blood within the brain may cause severe neurologic complications or death. A person who has a ruptured cerebral aneurysm may complain of the sudden onset of "the worst headache of my life."
