A brain aneurysm is an aneurysm that occurs in the brain. An aneurysm is the bulging of an artery that results from weakness in the artery's wall. The major complication of aneurysms is that the wall can become so weak that the aneurysm ruptures, causing hemorrhage that can ultimately lead to death if not treated quickly.

There are generally two classes of brain aneurysms: berry (saccular) aneurysms and Charcot-Bouchard aneurysms. Berry aneurysms have a tendency to occur in families (eg, in association with a disease called polycystic kidney disease), although they are less commonly associated with hypertension (high blood pressure). They most commonly occur in the circle of Willis, a major system of arteries that provides blood to the brain. Since the circle of Willis is outside of the brain, ruptured berry aneurysms don't frequently cause intracerebral (within the brain) hemorrhages; they usually cause subarachnoid hemorrhages.

Charcot-Bouchard aneurysms, on the other hand, are most commonly associated with hypertension and typically occur in the small arteries that penetrate into the brain. As a result, a ruptured Charcot-Bouchard aneurysm leads to an intracerebral hemorrhage.

"An aneurysm is a localized , blood-filled dilation of a blood vessel caused by disease or weakening of the vessel wall." They most often occur around the brain and heart.

An aneurysm is a bulging of part of a blood vessel, most commonly in the blood vessels of the brain, due to weakening of the walls of the blood vessel and/or blood pressure over time.

A ruptured aneurysm is when the aneurysm breaks open, and is an extreme emergency. Unless treated immediately, such events are often fatal, as they result in massive internal bleeding, hypovolemic shock, etc.. If this occurs in the brain, the additional bleeding inside the dura mater and skull will cause increased pressure on the brain, which can result in death.

What causes cerebral aneurysms?

Cerebral aneurysms are usually aneurysms we are born with. There are certain conditions, however, that can predispose one to develop aneurysms later in life. Hypertension can cause small aneurysms in the brain stem and midbrain that can bleed - these usually are not able to be seen because they are so small, however. Another possible cause is infections. These aneurysms are called mycotic aneurysms and are the result of infectious material, or emboli, being lodged in the cerebral arteries, causing a localized infection and weakening of the artery walls, leading to aneurysmal formation.
