Multimodal Imaging Findings Associated With Cardiac Oxalosis Cardiomyopathy

We report the case of a 50-year-old woman with secondary oxalosis following bowel resection resulting in restrictive cardiomyopathy and a diagnosis of cardiac amyloidosis based on the initial workup. The case documented findings by cardiac magnetic resonance imaging and technetium Tc 99m–labeled pyrophosphate scan in patients with cardiac oxalosis, which can mimic findings in cardiac amyloidosis, expanding the differential diagnosis.
