Long-term follow-up of a rare calcified cardiac tumor: a case report

Abstract

We describe a case of cardiac masses (high- and iso-echoic mass) which were detected by echocardiography in a 57-year-old man with cerebral infarction. Because he refused both biopsy and surgery, the patient was treated with an anticoagulant and antibiotic in our outpatient clinic. During 3-year follow-up, the iso-echoic mass disappeared and the high-echoic mass did not change. Thus, we considered the iso-echoic mass a thrombus and the high-echoic mass a benign tumor. Cardiac computed tomography revealed that the high-echoic mass had extensive calcifications like phleboliths, and magnetic resonance imaging pattern coincided with that of hemangiomas. We conclude that the benign tumor/high-echoic mass might be a vascular malformation.
