Figure 3

CT (top), PET (middle), and PET/CT (bottom) scans of patient number 3. (a) Intense inhomogeneous ¹⁸F-FDG uptake in left nasopharyngeal primary mass and asymmetric diffuse soft-tissue thickening in nasopharynx ( 8.2). (b) Multifocal uptake in liver correlating with multiple cystic lesions on CT ( 5.2). (c) ¹⁸F-FDG uptake in ilium (bone marrow, 5.0).
