title: Myocardial uptake of a bone tracer associated with hypercalcemia.
abstract: A patient with end-stage renal disease and hypercalcemia was referred for a radionuclide bone imaging study. Deposition of Tc-99m hydroxymethylenediphosphonate was apparent in the lungs and myocardium as well as in the skeleton. Renal uptake was also noted, despite anuria. Computed tomography demonstrated nephrocalcinosis but no myocardial calcification. The cause of myocardial uptake of tracer is unknown. Amyloidosis is suggested as a possibility but is not validated in this case.
