Overview
Cerebral Aneurysms
A cerebral aneurysm (better known as a brain aneurysm) is a weak or thin spot in a brain artery wall that balloons out, filling with blood. This bulging aneurysm risks rupturing or bursting. If it does, the blood from the aneurysm spills into the surrounding tissue, which is known as a subarachnoid hemorrhage and can lead to stroke, brain damage or death.
Symptoms
An unruptured cerebral aneurysm often exhibits no symptoms at all. If the aneurysm is large enough, some symptoms may include:
- Headache
- Dilated pupil
- Double vision
- Numbness on one side of the face
- Pain behind the eye
