Abstract

Benign mature teratomas are the most common type of germ cell tumors that arise in the anterior mediastinum. Intrapericardial teratomas are a rare manifestation of this tumor type, which are generally diagnosed during infancy because of the heart compression symptoms they produce. Here we report a rare case of intrapericardial mature teratoma that was incidentally discovered in an asymptomatic 51-year-old woman.
