• A patient with enterococcal endocarditis and mitral valve vegetations showed focal activity in the mitral valve complex in images obtained with two bone-seeking radiopharmaceutials: technetium Tc 99m pyrophosphate and technetium Tc 99m medronate. Infective endocarditis is a rare cause of focal cardiac uptake in both infarct-avid myocardial scintigraphy and routine bone imaging.
