What is a cerebral aneurysm?
-
American Heart Association answered:Cerebral aneurysm, also called brain aneurysm, is a ballooning-out of the wall of an artery in the brain. Often this wall is weakened by disease, injury or defect present at birth. Aneurysms are often caused or made worse by high blood pressure. They aren't always life‑threatening, but serious consequences, such as stroke or death, can result if one bursts. A burst aneurysm is called a hemorrhagic (or bleeding) stroke. When a blood vessel on the brain's surface ruptures and bleeds into the space between the brain and the skull (but not into the brain itself), it's called a subarachnoid hemorrhage. When an artery inside the brain bursts, flooding the surrounding tissue with blood, it's called a cerebral hemorrhage.

Dr. William D. Knopf of Piedmont Heart Institute answered:A cerebral aneurysm (also known as an intracranial or intracerebral aneurysm) is a weak or thin spot on a blood vessel in the brain that balloons out and fills with blood. The bulging aneurysm can put pressure on a nerve or surrounding brain tissue. It may also leak or rupture, spilling blood into the surrounding tissue causing a hemorrhage. Some cerebral aneurysms, particularly those that are very small, do not bleed or cause other problems. Cerebral aneurysms can occur anywhere in the brain, but most are located along a loop of arteries that run between the underside of the brain and the base of the skull.

Dr. Joshua Bederson of The Mount Sinai Medical Center answered:An intracranial aneurysm ("cerebral aneurysm," "brain aneurysm") is a protruding bubble or sac on a brain artery that balloons out over time. Aneurysms have thin, weak walls and have a tendency to rupture causing hemorrhage into and around vital brain structures.An intracranial aneurysm ("cerebral aneurysm," "brain aneurysm") is a protruding bubble or sac on a brain artery that balloons out over time.
