Relative roles of radionuclide scanning and radiographic imaging in eosinophilic granuloma.

Twenty-four skeletal lesions were studied in seven patients with eosinophilic granuloma by radiographic skeletal surveys and radionuclide bone imaging. The radiographs detected 22 (92%) of these lesions and missed only two, whereas the scintiscans identified only 16 (67%) of these lesions, and missed eight. Radiographic skeletal survey and radionuclide bone imaging are complementary procedures in detecting bone lesions in bone marrow disorders, including eosinophilic granuloma. Use of either method alone is fraught with the danger of missing bone lesions of eosinophilic granuloma.
