Metastatic abdominal implants of endometrial carcinoma demonstrated on 99mtc-methylene diphosphonate bone scan.
Metastatic serosal and omental implants from a primary papillary endometrial carcinoma were well demonstrated by radionuclide uptake on a bone scan utilizing 99mTc-methylene diphosphonate. Imaging of an endometrial malignancy by a 99mTc-labeled phosphate compound has not previously been reported. While the exact mechanism of accumulation in such soft-tissue neoplastic foci is not known, several possibilities have been suggested. In this particular case, the mechanism appears related in some way to the presence of dystrophic calcifications within the metastatic deposits.
