ABSTRACT: Background: The discovery of a lethal or disabling malformation
requires a thoughtful decision in the event of a termination of pregnancy on
medical grounds. The termination of pregnancy can be selective in the
case of multiple pregnancies if a twin is suffering from a serious condition. Objective: To report a case of
anencephaly on a twin pregnancy and conduct a review of literature. Case: This is a 30-year-old woman carrying a pregnancy obtained after the third
attempt at in vitro fertilization (IVF) with transfer of two embryos. No risk
factor was found on this pregnancy except for the twinning. The diagnosis was made at
14 weeks +1 day during first term ultrasound, which discovered an on-going
bi-chorial bi-amniotic twin pregnancy, with twin B (TB) carrying a defect on
his head. A selective interruption was performed on TB at 16 weeks by cordonal
injection with potassium chloride. The pregnancy went on without incident and
with spontaneous vaginal delivery of the second twin at 39 weeks of pregnancy.
Despite the selective termination, the pregnancy went on without any
complication. Conclusion: Anencephaly on twin pregnancy is a rare occurrence.
In a bichorial pregnancy, a selective feticide can improve the gestational age at birth.
