[Barium granuloma of the rectum].

The authors report a case of barium granuloma of the rectum. This complication of barium enema is exceptional. During enema, the cannula may ulcerate the mucosa which is blown up secondarily by the barium. Clinically, the granuloma presents like a hard polyp which is suggestive in certain cases of a malignant tumour. The precise diagnosis is made by careful examination of the abdominal films before administration of barium taking in the whole of the pelvis.
