Clinical characteristics of patients at the time of 18FDG-PET/CT.
Fig 1.
A 78-year-old woman with diagnostic of elderly onset rheumatoid arthritis [EORA]. Fused 18F-FDG PET/CT and MIP images showed increased metabolism in aortic wall and supraortic vessels which corresponded to vasculitis. Increased 18F-FDG uptake in peripheral joints was also described with shoulder involvement. Inflammatory activity in the wrists was also observed, as a characteristic arthritis in this pathology.

Distribution of glycemic metabolism intake in patients diagnosed with polymyalgia rheumatica (PMR) and large vessel vasculitis (LVV).
Fig 3.
A 89-year-old woman 18F-FDG PET/CT with diagnostic of polimyalgia rheumatica. PET/CT images showed multiple mediastinal nodules with increase 18F-FDG uptake and bone marrow glucose hypermetabolism. The patient was finally diagnosed of in a lymphoproliferative process. No treatment was administered due to age and other concomitant pathologies.
