Cerebral Aneurysms
About the disease & condition
A cerebral aneurysm is a localized, abnormal weakening and outpouching of the wall of an artery in the brain, creating a sac-like or fusiform dilation. An unruptured aneurysm may be asymptomatic, while rupture leads to a subarachnoid hemorrhage (SAH), a life-threatening emergency.
Known Symptoms
- Often asymptomatic. Symptoms if large or compressing nerves: Headache, ocular palsies (e.g., third nerve palsy), visual field defects.
