A barium granuloma of the rectum, observed 6 and 9 months after a barium enema, was studied by light and electron microscopy. Mononucleated macrophages filled with electron dense material were located between the glands and the muscularis mucosae. No electron dense material was observed in the endothelial and epithelial cells. The difficulties in the identification of the material can in part be overcome with the use of electron microscopy.
