Brain Aneurysms

A brain aneurysm (also known as an intracranial aneurysm) is a weak spot on a blood vessel in the brain that bulges out and fills with blood. Brain aneurysms vary in size, shape and location and can occur in anyone, at any age although they are more common in adults than in children. People with certain inherited disorders are also at higher risk.

Aneurysms may rupture and bleed into the brain, causing serious complications, including hemorrhagic stroke, permanent nerve damage, or death if left untreated. Most brain aneurysms go unnoticed until they rupture or are diagnosed by brain imaging that may have been obtained for another condition.
