Fetal pericardial teratoma: presentation of two cases and review of literature.

We present the fetal ultrasound and echocardiographic findings and clinical outcome of two fetuses with intrapericardial teratoma encountered in our institution. In the first (diagnosed at 19 weeks of gestation) case there was elective termination of pregnancy; in the second case (diagnosed at 24 weeks), a pericardio-amniotic shunt was placed after reaccumulation of fluid following pericardiocentesis. We review the published experience of intrapericardial teratomas, focusing on the diagnosis, fetal echocardiographic findings, and outcome with and without prenatal intervention.
