The normal timing for first-trimester nuchal translucency screening of aneuploidies is 10 to 14 weeks' gestation. We describe a fetus with trisomy 18 that presented at 11 weeks with increased nuchal thickness. Reevaluation at 12 and 13 weeks showed early return to normal of the increased nuchal measurement.
