18F-FDG-PET confirms infective endocarditis by identifying an infectious right atrial mass in MRSA bacteremia.
Case Report (n=1)
18F-fluorodeoxyglucose-PET can be a useful imaging modality to confirm the diagnosis of infective endocarditis when presenting as a mass in an uncommon location such as the right atrium.
FDG-PET may aid right atrial endocarditis diagnosis in bacteremia; case report leaves open need for prospective validation before wider use.
We report a case of a 55-year-old male with a history of methicillin-resistant staphylococcus aureus bacteremia whose initial transesophageal echocardiography revealed a cardiac mass attached to the right atrium. Because of the uncommon location of the mass, 18F-fluorodeoxyglucose-PET was used to confirm the diagnosis of infective endocarditis.

Ramos et al. (2023) conducted a case report in Infective endocarditis (n=1). 18F-fluorodeoxyglucose-PET was evaluated on Diagnosis of the etiology of the right atrial mass. 18F-fluorodeoxyglucose-PET successfully identified a right atrial mass as infectious in origin in a 55-year-old male with MRSA bacteremia, confirming the diagnosis of infective endocarditis.
