Barium meal performed 12 days later, showing moderate dilatation of the oesophagus, stomach, and proximal duodenum (no much as seen on CT) with an intraluminal diverticulum within the duodeno-jejunal junction with smooth and regular wall, seen as a barium coated pouch within the barium filled duodenal lumen. giving the appearance of a "thumb of a glove". the diverticular neck seems to be at the ampullary region, as seen on CT. Beyond the proximal jejunal loops show normal appearance.
