A brain aneurysm, sometimes called a cerebral aneurysm, is a weak spot in a brain artery. The weak spot creates a balloon that fills with blood. The walls of the artery are weaker near an aneurysm, which means that the aneurysm can break open, or rupture. A ruptured aneurysm is a life threatening condition that can cause serious brain injuries or stroke. However, not all aneurysms rupture.
People with an aneurysm may need ongoing monitoring to ensure that it is not growing. A doctor may need to remove a larger aneurysm.
In this article, we provide an overview of brain aneurysms, including the types, symptoms, causes, complications, and treatments.
