Prenatal management of fetal intrapericardial teratoma: a systematic review.

Prenatal fluid drainage and other prenatal techniques have been utilized in the treatment of intrapericardial teratoma. While most fetuses tolerated pericardiocentesis, the neonatal benefit of this procedure is still uncertain, and outcomes of other interventions had variable success. Prenatal intervention for pericardial teratoma may be an option in specialized units but, given the maternal and fetal risks, needs careful consideration. © 2017 John Wiley & Sons, Ltd.
