We report the usefulness of F-FDG PET/CT for the detection and therapy evaluation of the infective vegetation. A 64-year-old man with history of aortic valve replacement presented with 2 months of fever without identifiable cause. Echocardiogram showed no inflammation vegetation or abnormality of mechanical valve function. FDG PET/CT with 50 IU/kg IV heparin revealed focal uptakes near the mechanical aortic valve. After antibiotics therapy, fever was ameliorated, and FDG PET/CT findings showed markedly decreased uptake of the lesions. FDG PET/CT is a powerful tool to detect endocarditis even in patients with no anatomical abnormalities.
