When barium extravasates into tissue during radiologic procedures such as barium enema, it is uptaken by macrophages and forms a granuloma. The result of this is a tumorous mass, fibrosis, and stricture (1), and a cancerous condition is sometimes wrongly suspected. In almost all cases of barium granuloma there is a history of barium enema, a fact which is helpful in making the correct diagnosis. We report a case of barium granuloma in which there was no history of barium enema or apparent rectal trauma.
