Vascular Disorders

A brain aneurysm is a balloon-like outpouching that forms because of a weakness in the wall of a brain blood vessel. Most aneurysms cause no symptoms; if one ruptures, it can lead to a life-threatening subarachnoid hemorrhage.

A cavernoma is a vascular malformation of the brain or spinal cord made up of thin-walled, dilated vascular spaces. It is usually benign but can cause symptoms such as bleeding or seizures.
