Myocardial uptake of Tc-99m MDP in chronic renal failure with cardiomyopathy

A uremic patient on hemodialysis, who had concurrent cardiomyopathy showed intense myocardial uptake of 99mTc-methylene diphosphonate (MDP). The presumed cause of uptake in the myocardium is metastatic calcification due to hypercalcemia secondary to the renal failure. However, supplementary mechanism caused by cardiomyopathy should be considered. We describe a case with bone tracer uptake in the myocardium in the absence of infarction in a patient with chronic renal failure.=20
