Anencephaly in a monochorionic monoamniotic twin pregnancy


Monochorionic, monoamniotic twin pregnancy. One twin with anencephaly and the other twin normal. 

Laser cord ligation was offered to the patient at the time of examination. Pregnancy outcome, however, is not known.

Twin pregnancy is associated with a higher rate of non-syndromic anomalies than singleton pregnancy, and this is particularly notable in monochorionic twins.
