A case of jejunal cancer showing images suspected superior mesenteric artery syndrome

Abstract

A 60-year-old woman visited our hospital complaining of epigastric discomfort, nausea and vomiting for 10 days. Although CT findings suggested superior mesenteric artery (SMA) syndrome, some of her physical characteristics mismatched the diagnosis. Further examinations including esophagogastroduodenoscopy and enhanced CT with foaming agent revealed entire circumference of the tumor with ulcer in the fourth portion of duodenum, pathological diagnosis was adenocarcinoma by biopsy. Laparotomy showed the tumor was located in jejunum, partial resection of jejunum was done. To avoid misdiagnosis of the SMA syndrome, we should carefully check any courses of duodenal dilatation with chronic upper abdominal symptoms. In this case, we could diagnose of the jejunal cancer correctly by detailed inspection.
