Ileal leiomyosarcoma and leiomyoma. False-positive scintiscans for Meckel's diverticulum

Two cases of ileal leiomyomatous neoplasms with positive scintigraphic findings for Meckel's diverticulum are presented. The precise mechanism for the abnormal concentration of the Tc-99m pertechnetate is uncertain. Illustrations of the collating barium and computerized tomographic studies are included and the scanning technique utilized is reviewed.
