Axial non-contrast
Infrarenal aortic aneurysm, maximally measuring 10.8 cm.
Left retroperitoneal stranding indicating aneurysm rupture. No active leak on arterial or delayed venous phase imaging (not included).
This also demonstrates the draped aorta sign - with the posterior wall of the aorta following the contour of the adjacent vertebral body as it decompresses into the soft tissues.
