Preschooler with anemia and a palpable epigastric mass

CT of trichobezoar
Coronal (above) and axial (below) CT with contrast of the abdomen show the stomach distended by a large mass that has a swirled appearance and that fills the entire stomach and the duodenal bulb.

The diagnosis was trichobezoar that after removal was found to have caused a gastric ulcer which eroded into the liver.
