PET-CT assessed the metabolic activity of the cardiac mass. a Positron emission tomography scan showed hypermetabolic activity (*) in the RA with a standard uptake value SUVmax of 21.2. b 18F-FDG PET-CT fusion image illustrates high FDG uptake of the cardiac mass (*). 18F-FDG PET-CT: F18-fluorodeoxy glucose-positron emission tomography
