CT scan showed a massively distended stomach, first, and second portions of the duodenum, after collapse of the third portion of the duodenum as it traverses the SMA (Figure 1). CT-angiography was obtained revealing acute angulation of the SMA-aortic takeoff at approximately 20 degrees (Figures 2 and 3).
CT angiography revealing severe acute angularity of the SMA-aortic take off. Black arrow: celiac artery; maroon arrow: aorta; blue arrow: superior mesenteric artery.
