Fig. 6From: Primary central nervous system post-transplant lymphoproliferative disorders: the spectrum of imaging appearances and differentialPrimary central nervous system post-transplant lymphoproliferative disorder. F-18 FDG PET exam demonstrates bilateral cerebral hypermetabolic lesions in the basal ganglia (arrows). The lesion on the left is larger but the lesion in the right basal ganglia had a higher SUVmax of 8.5 versus SUVmax of 7.2 in the left basal ganglia. Notice how hypermetabolic the cortex is and how this could obscure more peripheral lesionsBack to article page
