Cerebral aneurysm. Coloured 3D computed tomography (CT) angiogram of a cerebral aneurysm (swelling at centre left) in an artery in the brain of a 28-year-old woman. An aneurysm occurs when an artery wall weakens and swells. If it bursts, an aneurysm can cause severe internal bleeding. This image was obtained during interventional angiography to treat the aneurysm. The aneurysm is in a carotid artery at the level of the brain's anterior communicating artery.
