Morphological and functional imaging of the patient's bone lesions. A: Anterior-posterior x-ray image: focal bone loss of uncertain significance localized in the proximal and middle diaphysis of the left tibia. B: Sagittal and axial NMR images: focal alterations of the left tibia, both in the medullar and in the cortical portion, probably related to an inflammatory process. C: Coronal and axial NMR images: contrast-enhanced cortico-subcortical abnormalities in the middle-distal diaphysis of the left tibia. D: PET/CT fused images (coronal and axial): increased uptake of FDG in the diaphyseal cortex of the left tibia associated with structural alterations probably connected to inflammatory results.
