title: Intrapericardial teratoma with hydrops leading to in utero demise.
abstract: We report a case of intrapericardial teratoma following in utero demise at 29 weeks with nonimmune hydrops. The diagnosis was strongly suggested by ultrasound findings and confirmed by fetopathology. The mechanism whereby intrapericardial teratomas may lead to hydrops and death is massive pericardial effusion responsible for compressive tamponade. When prenatal diagnosis is performed before this stage, in utero interventions can obtain decompression, and the birth can be planned with rapid and appropriate management of the neonate.
