Intrapericardial teratoma masquerading as pyopericardium.

ABSTRACT

A 10-year-old boy was admitted with cardiac tamponade. Initial pericardiocentasis yielded pus. A subxiphoid tube-pericardiostomy was done and thick, purulent material was drained out. Subsequently, pericardiectomy was undertaken as features of pericardial constriction persisted. At surgery, however, an intrapericardial mass was discovered. Successful excision was performed and the patient made an uneventful recovery. Histopathology of the mass revealed features of an intrapericardial teratoma. Rarity of the lesion, and a hitherto unreported mode of presentation make this case worthy of documentation.
