Summary and Symptoms

An aneurysm is a bulging part of blood in an artery that is at risk of rupturing. There are also pseudoaneurysms, which are contained by the surrounding tissues. Aneurysms have little to no symptoms before rupturing. Some symptoms include pain behind the eye, vision changes, and paralysis on one side of the face. After a rupture people may feel pain, or a sudden, severe headache.
