technetium-tc-99m-sulfur-colloid and Sarcoma--Synovial

In a patient with synovial sarcoma, routine bone survey showed no abnormality, while bone marrow scintigraphy with Tc-99m sulfur colloid revealed a defect in the fifth lumbar vertebra. At surgery, tumorous invasion was noted in the fifth lumbar vertebra and the surrounding tissues. It was suggested that the bone marrow scintigraphy was particularly useful in the detection of tumorous invasion into the bone marrow at the early stage before the destruction of skeletal tissue.
