History  A 22-year-old man with a 12-year history of intermittent abdominal pain and diarrhea had an exacerbation of the diarrhea and weight loss. Representative roentgenograms of an air-contrast barium enema examination (Figs 1 and 2) are illustrated. A single-contrast barium enema study performed five years earlier had shown similar findings.

Diagnosis  Giant postinflammatory pseudopolyposis of Crohn's colon.

Comment  The supine roentgenogram from the air-contrast barium enema examination (Fig 1) demonstrated multiple sessile- and filiform-appearing polyps in the ascending, transverse, and descending colon. The sigmoid colon and rectum (not shown) were normal. A spot x-ray film (Fig 2) of the hepatic flexure showed a 5-cm polyp that had incorporated several filiform polyps. The presence of multiple filiform- and sessile-appearing polyps in a patient with a long history of gastrointestinal complaints indicative of inflammatory bowel disease should strongly suggest postinflammatory pseudopolyposis. The sparing of the rectosigmoid and asymmetric involvement of the more
