Ruptured abdominal aortic aneurysm with contrast extravasation

A ruptured infrarenal aortic aneurysm is identified with acute extravasation of contrast between the layers of chronic laminated thrombus. Extravasated blood can be seen in the posterior pararenal space (arrow), perirenal space (arrowhead), and in the anterior pararenal space (dashed arrow). The right kidney is displaced posteriorly.
