DIFFUSE HEMANGIOMA OF THE COLON

We report two cases of diffuse hemangioma of the colon in adolescent p atients. One patient had multiple phleboliths at the lower pelvis iden tified with plain radiographs of the abdomen. Several aspects were see n on double-contrast enema: luminal narrowing, colonic-wall thickening and submucosal colonic masses that changed in appearance with the deg ree of colonic distension. Angiography was inconclusive in one case. U se of CT and MR provided relevant information regarding the true exten t of the disease, but mr was superior in demonstrating unequivocally t he vascular nature of the lesions.
