Aneurysms

A cerebral aneurysm develops when a weakened area in an artery of the brain enlarges or bulges. If an aneurysm ruptures, it can cause serious bleeding around the brain.

Common Symptoms

• Sudden severe headache when rupture occurs

• Visual changes

• Pain around or behind the eye

• Nausea or vomiting

• Confusion or loss of consciousness

Diagnosis

CT angiography, MR angiography, and cerebral catheter angiography may be used to evaluate the location, size, and characteristics of an aneurysm.

Treatment

Management may include monitoring, microsurgical clipping, or endovascular procedures such as coiling depending on the aneurysm and its estimated risk of rupture.
