Aneurysm
An aneurysm is an abnormal bulging or ballooning in the wall of a blood vessel.
When to get help quickly: An aneurysm becomes urgent if it is leaking, ruptured, or causing sudden severe pain, collapse, or new neurological symptoms.
Common symptoms
Many aneurysms cause no symptoms, but some cause pain, a pulsating sensation, pressure effects, or neurological symptoms depending on where they are.
When imaging helps
Imaging helps show the aneurysm's size, shape, exact location, and whether it has features that increase the risk of rupture or treatment need.
What radiology does
CT angiography, MR angiography, ultrasound, or conventional angiography can help show its size, location, and risk features.
What usually happens next
Management ranges from monitoring to endovascular treatment or surgery depending on the vessel, size, symptoms, and rupture risk.
