Ectopic pancreas and intestinal volvulus

1. Abdominal and pelvic computed tomography (CT) described a volvulus in the duodenal–jejunal transition with evidence of intestinal malrotation with the corkscrew sign (Figure 1A); inversion of the superior mesenteric vein and artery (Figure 1B); complete abdominal rotation with the colon on the right and the Treitz also on the right (Figure 1C). These findings were associated with duodenal and gastric dilation upstream. There was also the presence of a nodular lesion at the pyloric region with nearly 22 mm (Figure 2). 2. Upper endoscopy: presence of a polypoid mass with a central umbilicus localized in the great curvature of the prepyloric region.
