Abstract

The fetal triploidy syndrome presentations include intrauterine growth retardation, hydrocephalus, oligohydramnios, and cystic changes of the placenta. Although the majority of triploid conceptions abort spontaneously in the first trimester, rarely they progress to term. Determination of the karyotype is important for the management of a pregnancy with a live fetus, and has implications for genetic counseling of subsequent pregnancies. We present a case of fetal triplody syndrome with large placental cyst and hydrocephalus.
