Aneurysms do not always cause symptoms. They are often noticed during routine medical exams. Many are found during diagnostic procedures for other problems.

Symptoms depend on where the bulge is. A pulsating sensation may be felt. Pain is caused from the pressure on surrounding organs. Aneurysms in the brain may cause vision problems or headaches. An aneurysm in the chest may affect swallowing or might cause chest pain if it presses on the lungs. An abdominal aortic aneurysm might cause pain in the back or the groin. Most people are unaware of an aneurysm until it begins to leak or rupture, and then they describe the pain as severe or tearing.
