Clinical, radiographic and scintigraphic abnormalities in primary oxalosis of a 52 years old female are demonstrated. Severe oxalosis-nephropathy and oxalosis-arthropathy/enthesiopathy are shown. For the first time an intense myocardial uptake of 99 m Tc-HDP and 99 m Tc-MDP is described in connection with oxalosis. It is suggested that in the appropriate clinical setting this pattern may be suggestive of oxalosis-cardiomyopathy. Review of literature.
