A 65-year-old woman presents with fever and dyspnoea 6 years post-mechanical aortic valve replacement and aortic root replacement for a type A aortic dissection. Blood cultures grew S. aureus, and the patient was referred for a TOE, which was equivocal. (a) Axial and (b) coronal fused 18 F-FDG PET/CT images and (c) coronal unfused 18 F-FDG PET images demonstrate intense FDG around the prosthetic aortic valve and at the aortic root (arrow) consistent with prosthetic valve endocarditis. The patient underwent reoperation for aortic valve replacement and aortic root repair
