Echocardiographic features in a patient with primary oxalosis

Primary oxalosis is a rare congenital disorder of oxalate metabolism characterized by deposits of calcium oxalate in several organs, including the heart. We present the case of a 38-year-old man with primary oxalosis who had unique echocardiographic findings. Two-dimensional echocardiography revealed the sparkling high intensity echocardiographic pattern and concentric thickening of myocardial walls. Microscopic examinations showed the extensive deposits of calcium oxalate crystals in the myocardium. Therefore, we suggest that primary oxalosis should be given important consideration in the differential diagnosis of a hypertrophied myocardium with high intensity echocardiograms.
