Intrapericardial Teratoma Diagnosed on CT

Abstract

Intrapericardial teratomas are rare tumors which usually present in infancy. These tumors may be life-threatening because of the associated large pericardial effusion and cardiac compression. Here we present a case of intrapericardial teratoma which presented with cardiac tamponade in a neonate and was diagnosed using multidetector spiral computed tomography. The imaging features, clinical presentation, and differential diagnosis of this seldom-encountered entity are discussed.
