title: Hematochezia and the false negative Meckel's scan: a continued need for barium studies.
abstract: A patient with hematochezia and a false negative Meckel's scan is presented. A Meckel's diverticulum was subsequently diagnosed on barium small bowel follow-through. Meckel's diverticulum is discussed with emphasis on the relationship of barium and radionuclide studies.
