Monochorionic-Monoamniotic Twins Discordant for Anencephaly: Story of Expectant Management

Monochorionic-monoamniotic (MCMA) twin pregnancy discordant for anencephaly is a rare occurrence. Selective reduction versus expectant management is itself a debatable topic. We report such a case managed expectantly with successful outcome. A 30 years old second gravida woman was referred to us with MCMA twin pregnancy discordant for anencephaly at 18 weeks of gestation. She opted for expectant management till 33 weeks when cesarean section was performed for preterm onset of labor. Surviving female neonate weighing 1580 g required nursery care for seven days and was discharged in good condition. She did not have any congenital malformation. Female neonate with anencephaly weighing 1000 g was provided with compassionate care and she died within one hr of birth. This report advocates for the option of expectant management for such a rare condition.
