Unusual extraosseous tumoral accumulation of 99mTc-MDP.
Three cases (rhabdomyosarcoma, lymphoma, and metastatic malignant melanoma) of unexpected increased uptake of methylenediphosphonate labelled by technetium 99m sodium pertechnetate (99mTc-MDP) are described. The possible mechanisms of the extraosseous tumoral accumulation of 99mTc-MDP in these malignancies are discussed. The usefulness of this method for the diagnosis, localization, and follow-up of some extraosseous tumors is evaluated.
