(A,B) A 10-year-old girl with typical PET/CT findings of osteoblastoma; (A) Axial CT revealed osteolytic bone destruction in the right vertebral plate of the fifth cervical vertebra, with nodular ossification at the center of the lesion (arrow); (B) The PET/CT fusion image of the corresponding area shows increased 18F-FDG uptake (arrow), with a SUVmax of 8.1. (C–F) A 18-year-old man with atypical PET/CT findings of osteoblastoma; (C) Axial CT revealed osteolytic bone destruction in the fourth cervical vertebra, with the main lesion located in the vertebral body and multiple residual bone ridges visible within the lesion (arrow); (D) The PET/CT fusion image of the corresponding area shows increased 18F-FDG uptake (arrow), with a SUVmax of 6.8; Sagittal (E CT; F PET/CT) reveals compressive changes of the vertebral body (arrows).
