Infant with bilious vomiting

UGI of false positive malrotation with midgut volvulus
Early AP image from an UGI exam (above) showed the ligament of Treitz to project over the midline of the spine and at the same level as the duodenal bulb. Later image (below left) showed the proximal jejunum in the right upper quadrant. Final image (below right) after following contrast through to the colon showed the cecum to be on the right side of the abdomen but to be high in position. The patient was surgically explored and in the operating room the ligament of Treitz was seen in the left upper quadrant and there was normal rotation of the bowel.

The diagnosis was false positive diagnosis of malrotation with midgut volvulus.
