Aneurysms form in areas where the artery wall becomes thin or weak. Thinning artery walls and resulting aneurysms can be caused by a number of factors. Common causes include:
- Congenital (present at birth) weakness in artery wall
- High blood pressure
- Infection
- Trauma or injury to the brain
- Tumor
- Plaque build-up on artery walls
