title: Rectal juvenile polyp detected on (99m)Tc-pertechnetate abdominal scintigraphy (Meckel scan).
abstract: An 8-year-old boy presented with first episode of rectal bleeding. Initial hemoglobin was 9 g/dL. A Meckel scan showed a hyperemic focus in the lower pelvis. Colonoscopy identified a juvenile polyp with dysplasia in the rectosigmoid region. It is important to carefully evaluate the dynamic flow images in the Meckel scan because pathology other than a Meckel diverticulum may be identified.
