Survival of a profoundly hydropic fetus with a sacrococcygeal teratoma delivered at 27 weeks of gestation for maternal mirror syndrome.

The development of hydrops fetalis and maternal mirror syndrome in the setting of fetal sacrococcygeal teratoma (SCT) carries a grave prognosis. Fetal surgery is not typically offered for hydropic fetuses beyond 26 weeks of gestational age. Few options exist for these families, and they are typically counseled to continue pregnancy until delivery is necessary for maternal indications or the fetus is 30 weeks old. Although a number of series report the survival of hydropic SCT infants delivered after 30 weeks of gestation, a paucity of information is available regarding the outcome of hydropic SCT infants delivered between 26 and 30 weeks of gestation. We now report successful postpartum resection and survival of a hydropic fetus delivered at 27 weeks for maternal mirror syndrome that may assist in counseling families in similar situations.
