Arterial aneurysm
An outpouching (aneurysm) of an artery. As opposed to a venous or cardiac aneurysm. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word “aneurysm” comes from the Greek “aneurysma” meaning “a widening.”

aneurysm in the wall of an artery; the chief signs are formation of a pulsating tumor, often a bruit (aneurysmal bruit) heard over the swelling, and sometimes symptoms from pressure on contiguous parts.
