Abdominal aortic aneurysm detected measuring 4.7cm x 4.9cm in maximal dimension at the L2 vertebral body extends from below the level of renal artery origins to above the aortic bifurcation.. Large right sided retroperitoneal haematoma appears to arise from this segment of the abdominal aorta. This haematoma measures 10cm (AP) x 8.4cm (trans) x 12.6cm (SI) and displaces the right kidney laterally. There is a small/moderate amount of free intraperitoneal fluid within the pelvis.
Conclusion
Ruptured abdominal aortic aneurysm, with a large retroperitoneal haematoma.
