Cardiac Tuberculosis on 18F-FDG PET Imaging—A Great Masquerader of Cardiac Sarcoidosis

A young gentleman with suspected cardiac sarcoidosis and LV dysfunction whose CMR revealed multifocal subepicardial to mid myocardial linear enhancement in the left ventricular myocardium underwent cardiac 18F-FDG PET imaging. The images revealed patchy regions of increased FDG uptake involving the...
