An aneurysm attached to the vascular lumen by a mouth is called which type?

Explanation:
In aneurysm morphology, a pouch-like bulge that remains attached to the vessel by a narrow neck, described as a mouth, is the hallmark of a saccular aneurysm. This contrasts with a fusiform aneurysm, which involves dilation of the entire vessel circumference without a distinct neck; a dissecting aneurysm, which results from a tear in the vessel wall creating a false lumen; and a mycotic aneurysm, which is driven by infection and can be either shape but is defined by its infectious origin rather than the necked pouch appearance. So the described attachment by a narrow neck points to a saccular aneurysm.
