Twin pregnancy with one normal fetus and one complete hydatidiform mole: Outcome of expectant management

Twin pregnancy with one fetus and one complete mole falls amongst extremely rare obstetric situations. The spectrum of complications associated with it is wide. Once diagnosed, the choice between continuation and termination of pregnancy depends upon couple's preference and readiness to accept possible complications. Key to success lies in clinical vigilance and tailoring management according to emerging needs during pregnancy and follow up. We present a case of twin pregnancy with complete hydatidiform mole and coexisting normal fetus diagnosed at 25 weeks. Pregnancy was complicated by anemia, gestational diabetes mellitus, recurrent vaginal bleeding, intrauterine growth restriction and iatrogenic preterm delivery.
