Original Articles: PDF OnlyDetection of Cecal Adenocarcinoma by Tc-99m Pertechnetate ScintigramGARDNER, RICHARD C., M.D.; KANTROWITZ, PAUL A., M.D.; CHANDLER, HAROLD L., M.D.Author Information From the Department of Medicine, Mount Auburn Hospital, Cambridge, Massachusetts Clinical Nuclear Medicine: October 1984 - Volume 9 - Issue 10 - p 577-578 Buy 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. © Lippincott-Raven Publishers.
