Prosthetic Valve Endocarditis Diagnosed by 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

A 74-year-old man with a history of prosthetic aortic valve replacement 4 years before presentation was evaluated for a fever since the previous day. Although multiple blood cultures were positive for penicillin-susceptible Streptococcus gordonii, an oral viridans streptococcus vegetation was not detected by echocardiography, and the modified Duke criteria for infective endocarditis were not met. Despite treatment with penicillin G (18 million units daily) for 2 weeks after negative blood cultures, 4 days after the last dose blood cultures turned positive for the identical organism.
