A brain aneurysm is a bulge in a blood vessel in the brain. It often looks like a berry hanging on a stem. An aneurysm can leak or rupture, causing bleeding into the brain(hemorrhagic stroke).
A ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment.
Most brain aneurysms, however, don’t rupture, create health problems or cause symptoms. Such aneurysms are often detected during tests for other conditions.
