According to the Mayo Clinic, an aneurysm is likely to go undetected until it either ruptures or shows up on a brain imaging test that you might undergo for another condition.

from undetected aneurysms. Screening will allow most people who have a rupture and might die from an aneurysm to receive proper treatment before an emergency exists.
