An aneurysm (or aneurism) (from Greek ανευρυσμα, a dilatation) is a localized dilation or ballooning of a blood vessel by more than 50% of the diameter of the vessel. Aneurysms most commonly occur in the arteries at the base of the brain (the circle of Willis) and in the aorta (the main artery coming out of the heart) - this is an aortic aneurysm. This bulge in a blood vessel, much like a bulge on an over-inflated innertube, carries the risk of bursting and leading to internal hemorrhage. The larger an aneurysm becomes, the more likely it is to burst.
The layer of the artery that is in direct contact with the flow of blood is the tunica intima, commonly called the intima. This layer is made up of mainly endothelial cells. Adjacent to this layer is the tunica media, known as the media. This "middle layer" is made up of smooth muscle cells and elastic tissue. The outermost layer (farthest from the flow of blood) is known as the tunica adventitia or the adventitia. This layer is composed of connective tissue.
Types
Aneurysms are also described according to their shape: Saccular or fusiform. A saccular aneurysm resembles a small sack; a fusiform aneurysm is shaped like a spindle. More on [ Aneurysm ]

@carolinefo Even if it gave me an instant aneurysm I'd probably still wolf it down.

@CherylWalls That's OK, I understand. I'm assuming that they think it may be an aortic aneurysm?
