case_images: An upper gastrointestinal contrast study was suggestive of intestinal malrotation: duodenojejunal flexure was demonstrated to the left of the midline with the stomach on the right; the proximal small bowel was on the left side of the abdomen ( Fig. 1 ). 
case_images: Intraoperative aspect: preduodenal portal vein crossing the second part of the duodenum. D1, first part of the duodenum; D2, second part of the duodenum; GB, gallbladder; PDPV, preduodenal portal vein.

case_images: The stomach and duodenum proximal to the PDPV were distended adequately by air; however, the duodenum distal to the aberrant crossing vein remained collapsed signifying the presence of extrinsic compression ( Fig. 2 ).
