Figure 1 Initial computed tomography performed at local hospital before the onset of hypotension. A: Plain computed tomography (CT) demonstrating dilated descending aorta and hyperattenuated collection located eccentrically within the aortic wall (arrow); B: Contrast-enhanced CT revealed crescentic and asymmetric wall thickening of the descending aorta: Contrast is not visualized within the aortic media. Intimal flap was not detected; C: An aneurysm at the anteroinferior pancreaticoduodenal artery (arrow); D: The occluded root of the coeliac artery (arrow).
