title: Placentomegaly due to fetal congestive failure in a pregnancy with a sacrococcygeal teratoma.
abstract: Conditions associated with placentomegaly in which the disproportionate placental enlargement is understood include erythroblastosis fetalis, intrauterine infections and chorioangioma. This report suggests that in a pregnancy complicated by a large sacrococcygeal teratoma, placentomegaly results from high-output fetal cardiac failure secondary to the mass acting as an arteriovenous fistula.
