Figure 1

18F-FDG PET/CT axial (left), sagittal (middle) and coronal (right) fused view of right knee in patient no. 1. The first PET/CT performed at time of first relapse of GCTB (lower row) showed a focal area of intense FDG uptake (SUVmax = 21) corresponding to a lytic lesion of the medial meta-epiphyseal aspect of the right femur, showing extension to the neighbouring soft tissue. A second PET/CT scan (upper row), showed a disease relapse with an FDG avidity lower than original lesion (SUVmax = 11). A = anterior; R = right; H = high.
