False-positive imaging of Tc-99m pertechnetate Meckel's scintigraphy in a patient with hemorrhagic enteritis

Abstract

An 11-year-old boy was hospitalized with abdominal pain, melena, and vomiting. His clinical manifestations and laboratory data suggested infectious enteritis or Meckel's diverticulum. A test for veto toxin was slightly positive, and Tc-99m pertechnetate scintigraphy showed no abnormal findings except for extensive radioactivity in nearly the entire colon. A few days later, acute renal failure, thrombocytopenia, and hemolytic anemia appeared. These are typical signs of the hemolytic uremic syndrome.
