Intrapericardial Teratoma in Newborn Infant Revealed by Cardiac Tamponade

A 15-day-old boy presented with signs of heart failure and tamponade. Two- dimensional echocardiography revealed a complex intrapericardial mass (47 mm x 36 mm) with a large pericardial effusion compressing the heart. A CT scan defned the relationship with great vessels, pericardium and myocardium. Complete surgical resection was performed without complication. Histology of the tumor confrmed the presumptive imaging diagnosis of teratoma. Intrapericardial teratomas are rare primary cardiac tumors usually diagnosed in neonates and infants. They contain endodermic, mesodermic, and neuroectodermic germinals layers. Intrapericardial teratomas are usually benign tumors but may be life-threatening because of pericardial effusion and heart compression. Echocardiography was used to make a diagnosis by showing a intrapericardial heterogeneous mass compressing the heart. Bi-dimensional echocardiography was a performed exam in primary cardiac tumors diagnosis, but tomodensitometry (CT scan) and magnetic resonance imaging (RMI) have advantages in large tumors assessing the relationship between the tumor and adjacent tissues
