Abstract
Osteoblastoma accounts for approximately 1% of all primary bone tumors. We report F18-fluorodeoxyglucose positron emission tomography/computed tomography (F18-FDG PET/CT) findings of an osteoblastoma in the rib of a 20-month-old girl child, who had fever with pain in the right shoulder for 4 months. This lesion was initially judged as a malignant bone tumor but a biopsy revealed it to be an osteoblastoma. The age of patient and predominant site of disease involvement contributes to uniqueness of our case. In our case, F18-FDG PET/CT has facilitated biopsy planning and ruled out other sites of disease involvement.
