Radiological and 18F-Sodium fluoride (18F-NaF) positron emission tomography-computed tomography (PET/CT) images of a 37-year-old male patient who had a fracture of the left medial and posterior malleolus of the tibia. a-d Initial images of plain radiographs and computed tomography (CT); a ankle anterior-posterior view, b ankle lateral view, c ankle CT coronal view, d ankle CT lateral view. Note that the fracture involved the talocrural (tibiotalar) joint. e, f Plain radiographs after internal fixation with a metal pin. g-i Plain radiographs performed at 17 months after injury presents pin removal status and osteoporotic changes around the ankle joint, but does not provide any information about the degree of ankylosis in the ankle. j-l) 18F-NaF PET/CT shows hot uptake around the talocrural joint near the initial fracture area
