A Barium Granuloma of the Rectum Which Was Diagnosed by Endoscopic Mucosal Resection / 대한소화기내시경학회지

A barium granuloma of the colon and rectum is a rare complication of radiologic examination of the digestive tract using barium. This complication is exceptional. During the enema, the cannula may ulcerate the mucosa which is blown up secondarily by the barium. Clinically, the granuloma presents as a hard polyp like a malignant tumur. So, the recognition of this entity is important because it can mimic other lesions including a neoplastic process endoscopically. Moreover, hisological findings, though they may be characteristic, often go unnoticed with routine techniques only. The authors report a barium granuloma of the rectum which was diagnosed by endoscopic mucosal resection and radiographic study of the paraffin block.
