A 29-year-old pregnant woman with parity 0-0-0-0 was diagnosed with
monoamniotic twin pregnancy discordant for anencephaly at 14 weeks
gestation. Umbilical cord entanglement, which is an important cause of
fetal death in monoamniotic twins, was confirmed by three-dimensional
ultrasound. Cesarean section was performed at 34 weeks of gestation, and
the normal newborn infant was discharged without any complications. We
report a case of monoamniotic twin pregnancy discordant for anencephaly
and diagnosed with cord entanglement by three-dimensional ultrasound at
14 weeks of gestation, and now report it along with a literature review.
