Figure 3. A second[¹⁸F]-FDG PET [(a) maximum intensity projection (MIP); and (b) whole body sagittal slice] performed after 10 weeks of corticosteroid therapy shows complete disappearance of the pathological [¹⁸F]-FDG foci depicted on the first PET scan. (c) The CT part of the PET/CT examination still shows osteoblastic lesions. (d) Contrast-enhanced multidetector row CT scan performed after 10 weeks of treatment with oral corticosteroids shows resolution of leptomeningeal enhancement over the clivus (sagittal slice) and (e) normalization of the appearance of the pituitary gland (coronal slice), as compared with Figure 1.
