[Intrapericardial teratoma in an adult].

The intrapericardial teratoma is a very rare congenital tumor of the heart which today is mostly diagnosed in early childhood using modern imaging devices. The course of a 46-year-old male who suffered from a pericardial effusion for the first time at the age of 13 is reported. During the subsequent three decades, the patient recurrently complained of chest pains. The final diagnosis was determined following surgical removal of the tumor and upon histological evaluation. The case reported here is unique because of clinical signs and symptoms of an intrapericardial teratoma documented in adolescence and adulthood over a period of 34 years.
