99-mTc-SF gastrointestinal scintigraphy used in recent years in the assessment of site and activity for ulcerative lesions, was shown to be very important for the diagnosis of a rare case of right colonic hemangioma. A young female patient suffering for some time from functional intestinal disorders, following negative radiologic and endoscopic findings, underwent 99-mTc-SF scintigraphy, which showed massive uptake of radioactivity in the ascending and right flexure of colon. A repeated colonoscopy with biopsy allowed the histologic diagnosis of capillary hemangioma.
