SMA syndrome

Superior mesenteric artery syndrome (SMA syndrome) refers to compression of the third portion of the duodenum between the aorta and SMA. The images above show classic CECT findings: there is dilation of the stomach, first and second portions of the duodenum (first image), with narrowing of the duodenum as it crosses the spine (second image) and collapse of the distal duodenum (third image).
