Brain aneurysm. Coloured magnetic resonance imaging (MRI) scan of an axial section through the brain of a 38-year-old patient,showing a large signal intensity (orange,centre) in the posterior cranial fossa,suggestive of a large aneurysm of the termination of the basilar artery. An aneurysm is a blood-filled dilation in a blood vessel wall. It is caused by a weakening of the vessel wall,which may be caused by hardening of the vessel (atherosclerosis),high blood pressure or injury. If left untreated an aneurysm can rupture,which is often fatal | |
