title: 99MTc-diphosphonate uptake in neuroblastoma.
abstract: Marked uptake of 99mTc-diphosphonate was noted in an extraadrenal neuroblastoma. Calcification was not demonstrable on radiographic or light microscopic examination, nor was crystalline material identified on electron microscopic examination; capillaries in the lesion appeared to be intact. Similar uptake of phosphate radiopharmaceuticals by a variety of lesions has been reported, and possible mechanisms for this phenomenon are discussed.
