Cerebral aneurysm. Coloured angiogram (blood vessel X-ray) of the brain and neck of a 28-year-old woman with a cerebral aneurysm (lower left) in a brain artery. An aneurysm occurs when an artery wall weakens and swells. The aneurysm is also shown as imaged by a coloured 3D computed tomography (CT) angiogram (orange). If it bursts, an aneurysm can cause severe internal bleeding. This large aneurysm is affecting the carotid arteries at the level of the brain's right middle cerebral artery.
