Brain Aneurysm Symptoms & Signs. A brain aneurysm is a bulging area within the wall of an artery that supplies the brain. In most cases, brain aneurysms do not produce symptoms. In some cases, the aneurysm may cause symptoms by pushing on other areas of the brain. Depending on the size of the aneurysm and the area involved, these symptoms can include headaches, neck pain, blurred vision, and speech changes.
Aortic aneurysms often cause no symptoms at all. But if present, symptoms include: 1  Tearing pain in the chest, abdomen, and/or middle of the back between the shoulder blades.2  Thoracic aneurysms may cause shortness of breath, hoarseness, cough (due to pressure on the lungs and airways), and difficulty swallowing (pressure on the esophagus). thoracic aneurysm may cause a heart murmur. An abdominal aneurysm feels like a pulsating mass in the stomach. If one is detected, it must be monitored. Aneurysms are at higher risk of rupture as they grow larger.
