Teenager on an exclusively vegetable-protein-xanthum diet with increasing abdominal distension and vomiting

AXR and CT of phytobezoar
AXR (left) shows a mottled structure filling the entire width of the upper abdomen. Coronal CT with contrast of the abdomen (middle and right) shows the structure is the stomach distended with particulate material. The patient was given cellulase and an AXR one day later showed the stomach to be empty.

The diagnosis was phytobezoar.
