Cerebral aneurysm is a permanent protuberance, that is, a focal dilatation of an arterial vessel in the brain at which the wall stretches, thinning and forming a bubble. It can result in rupture of the wall at the point where the vessel is most fragile or thinned, causing hemorrhage. Blood loss in the brain can be a cause of hemorrhagic stroke.
