Diagnostic red blood cell scintigraphy in GI tract bleeding from an intestinal hemangioma.

99mTc-labeled red blood cell (RBC) scintigraphy in vivo established the diagnosis of intestinal hemangioma in a 6-year-old girl suffering from gastrointestinal (GI) tract bleeding who had undergone an operation for removal of hemangioma at the nail bed. Other examinations, double-contrast barium meal study and angiography, were unsuccessful in making the diagnosis. Intestinal hemangioma is rare in childhood, but a useful technique such as RBC scintigraphy should be performed to find the bleeding point of the GI tract, especially in case the patient has another obvious hemangioma.
