technetium-tc-99m-sulfur-colloid and Leiomyosarcoma

Jejunal leiomyosarcoma was initially detected in a patient by a gastrointestinal bleeding scan with Tc-99m sulfur colloid (SC). The scan showed increased blood flow and delayed persistent accumulation of radiotracer in the tumor. The Tc-99m SC gastrointestinal bleeding scan provided useful information to help determine the differential diagnosis of gastrointestinal tumor with bleeding.

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.
