Brain Aneurysm
Also called: Berry aneurysm, Cerebral aneurysm, Intracranial aneurysm
A brain aneurysm is an abnormal bulge or "ballooning" in the wall of an artery in the brain. They are sometimes called berry aneurysms because they are often the size of a small berry. Most brain aneurysms produce no symptoms until they become large, begin to leak blood, or rupture. If a brain aneurysm presses on nerves in your brain, it can cause signs and symptoms. These can include:
Treatment depends on the size and location of the aneurysm, whether it is infected, and whether it has ruptured. If a brain aneurysm ruptures, symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, loss of consciousness, and signs of a stroke. Any of these symptoms require immediate medical attention. National Heart, Lung, and Blood Institute
