We present the case of a 30-year-old woman scanned at 13 weeks GA after in vitro fertilization. Her medical history was noncontributive. We found a dichorionic pregnancy.  Fetus A (closer to the internal os) had a normal nuchal translucency (1 mm). Fetus B presented with acrania and encephalocele. The nuchal translucency of fetus B was 4 mm. The parents chose selective interruption of pregnancy.
