title: Non-ossifying fibroma mimicking distant metastasis of osteosarcoma on (99m)Tc-methylene diphosphonate bone scintigraphy: Diagnosis with single photon emission tomography/computed tomography.
abstract: Non-ossifying fibromas (NOFs) are benign bone lesions with variable appearance on bone scintigraphy. Single photon emission tomography/computed tomography (SPECT/CT) can help in accurate characterization of these lesions. We present a case of 14-year-old boy with recurrent osteosarcoma where NOF was mimicking distant metastasis on (99m)Tc-methylene diphosphonate bone scintigraphy. SPECT/CT was able to correctly characterize the lesion as NOF, thereby altering the management.
