Presentation
Vomiting and weight loss for 5 years.
Patient Data
Mildly distended stomach. Markedly distended second portion of the duodenum, with tapering of the third portion as it passes under the superior mesenteric artery.
Similar findings of mild gastric distention with more pronounced, moderate to severe dilation of the second portion of the duodenum, tapering as it crosses midline.
Case Discussion
Typical CT and fluoroscopic appearance of superior mesenteric artery syndrome, which occurs when there is extrinsic compression of the third portion of the duodenum due to a narrowed aortomesenteric angle.
This patient had a long treatment course which was complicated by infection from parenteric nutrition, eventually undergoing duodenojejunostomy to relieve symptoms.
