Preschooler with vomiting

AXR and upper GI of mesenteroaxial gastric volvulus
AXR AP (above left) shows a distended air-filled stomach which on the AXR upright (above right) has a large air-fluid level within it. AP image from an upper GI (below) shows that by following the course of the feeding tube the stomach appears to be upside down with the pylorus of the stomach located superiorly to the gastroesophageal junction and the tip of the feeding tube to be in the second part of the duodenum.

The diagnosis was mesentero-axial gastric volvulus.
