title: Scintigraphic appearances of osteoid osteoma.
abstract: A series of 42 osteoid osteomas is reviewed, and the scintigraphic appearances are described. In all cases, a marked, well-localized area of increased activity was demonstrated at the tumor site in both the blood-pool and standard two-hour images. The blood-pool images were performed after the injection of technetium-99m methylene diphosphate which showed a small hyperemic lesion in all cases of osteoid osteoma, thus distinguishing this tumor from other lesions which may show uptake of radionuclide activity after two hours.
