title: Detection of cecal adenocarcinoma by Tc-99m pertechnetate scintigram.
abstract: A 23-year-old male presented with occult gastrointestinal bleeding and iron deficiency anemia. A Tc-99m pertechnetate abdominal scan was positive and surgery revealed an adenocarcinoma of the cecum. No Meckel's diverticulum was identified. This is the first reported association of an abnormal Tc-99m pertechnetate scan in adenocarcinoma. Carcinoma of the right colon should be considered in any patient with a positive pertechnetate scan for Meckel's diverticulum and suggestive clinical features.
