Iliac artery aneurysm: Focal or diffuse dilatation > 1.5x normal respective iliac artery diameter
Regarded as aneurysmal if ≥ 25 mm in diameter
Fusiform aneurysm: Diffusely and circumferentially involves lengthy arterial segment
Saccular aneurysm: Focally involves arterial segment; appears as focal outpouching or bulge
True aneurysm contains all 3 arterial wall layers
Most commonly due to atherosclerosis
False aneurysm (pseudoaneurysm) does not contain all 3 layers of arterial wall
Focal or diffuse disruption of arterial wall
Causes include iatrogenic or penetrating trauma, contained rupture, vascular infection (mycotic)
