Disseminated bone marrow metastases from primary breast cancer: detection and follow-up by radioimmune bone marrow scintigraphy.

Bone scintigraphy of a 40-yr-old patient suffering from primary breast cancer suggested the possibility of diffuse metastases. Bone marrow scintigraphy using 99m Tc-labeled monoclonal antibodies (BW 250/183) demonstrated diffuse destruction of bone marrow due to metastatic disease and consecutive bone marrow extension. Bone marrow scintigraphy was highly sensitive in detecting progression of disease in this asymptomatic patient
