A 56-year-old woman presented with abdominal pain after undergoing a barium study for gastric cancer screening 2 days prior. On day 3 after the examination, she visited an emergency room and a glycerin enema was performed as the abdominal radiography revealed stagnation of barium in the pelvic region. On day 7 after the examination, she was referred to our department because of lower abdominal pain and a sensation of retained feces. Abdominal radiography revealed a small amount of barium pooled in the pelvic region and splenic flexure without free air. Colonoscopy revealed a deep ulcer with barium stagnation. The barium was removed with forceps. After 1 month, the ulcer lesion was covered elevated mucosa with dilated and tortuous surface vessels. Histopathology revealed inflammatory granulation. Five months after the initial colonoscopy, the elevated lesion was improved slightly and was incidentally biopsied. Histopathological findings remained unchanged. Eleven months after the initial colonoscopy, the elevated lesion was replaced by an ulcer scar.
