A patient with a benign calcified pulmonary focus concentrating 99mTc-methylenediphosphonate is described. To the best of our knowledge, this is the first description of the accumulation of 99mTc-phosphate compounds in a benign calcified focus of the lung. The value of a routine correlation with X-r

β¦ Synopsis
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.

A 2 1/2-year-old boy with a posterior mediastinal ganglioneuroblastoma was evaluated by bone scintigraphy using 99mTc-DMP and showed a marked increased uptake in the tumor mass. Although a routine chest X-ray and body CT scan failed to demonstrate calcification, X-ray examination of the removed tumo
Two cases of retrosternal multinodular goiter are described in which 99mTc-MDP concentrated. The possible etiology of this unexpected finding is briefly discussed in addition to the differentiation from other mediastinal tumors which may potentially accumulate 99mTc-MDP.
Two hundred and fifty-seven patients were studied with bone-seeking radiopharmaceuticals. They were randomly divided into three groups. Two groups were injected with two different 99mTc-methylene diphosphonates from two manufacturers (MDP 1 and MDP 2) and the third group with 99mTc-dicarboxypropane
