Fetal cardiac teratoma and pericardiocentesis: A case report

Fetal pericardial teratomas are rare. They present with pericardial effusion and hydrops. The definitive management is postnatal resection of the tumor. The exact antenatal management is not known due to its rarity. We present a case of fetal pericardial teratoma with pericardial tamponade. Pericardiocentesis performed at 31 weeks significantly relieved the venous compression, leading to resolution of hydrops and prolonging the gestational age for the definitive management.

Exact antenatal management is not known due to its rarity.What does this study add?Fetal pericardial teratomas with pericardial tamponade can be managed with a simple procedure such as pericardiocentesis. It can significantly relieve the venous compression, leading to the resolution of hydrops and helps in prolonging the gestational age for the definitive management. It can be considered as the first line management option in such cases.
