Blood tests revealed elevated levels of c-reactive protein (17. 79 mg dl−1) and serum tumour markers, such as carcinoembryonic antigen (cea, 10. 65 ng ml−1) and cancer antigen 19-9 (ca19-9, 29. 44 u ml−1). A small bowel series showed focal stricture in the distal jejunum with lobulated filling defect lesion and central barium collection (figure 1). An axial image of contrast-enhanced ct showed an approximately 7. 0 cm tubular mass in the left mid-abdomen, adjacent to the stricture site (arrow in figure 2a). A coronal reformatted image revealed focal stricture and circumferential wall thickening of the distal jejunum and dilatation of the proximal small bowel loop (figure 2b). A well-enhanced tubular mass was noted at the stricture site (arrow in figure 2b), and collapsed distal small bowel was well visualised (arrowhead in figure 2b). There were multiple enlarged lymph nodes in the small bowel mesentery around the superior mesenteric artery (sma) root. On small bowel enteroscopy, severe stenosis was identified at the distal jejunum showing oedematous and hyperaemic mucosal irregularities (figure 3). There was a small hole adjacent to the stricture; however, the orifice was so small that the enteroscope could not pass through it (arrow in figure 3). Given these imaging characteristics and the high serum cea and ca19-9, the differential diagnosis consisted of a small bowel adenocarcinoma with lymph node metastases, lymphoma or intestinal duplication with a high probability of malignancy.
