An obstetric ultrasound of a 38 years old woman with a dichorionic diamniotic twin pregnancy showed an increased nuchal translucency and absent nasal bone in one of the fetuses suggesting us an increased risk for Down Syndrome (DS). This fetus was detected to have trisomy 21 (47, XX+21) by investigation of the amniocentesis material and was selectively undergone feticide process at 20 weeks of gestation. The other fetus (46, XX) was successfully delivered at 36 weeks without any complications.
