We describe a case in which a patient presented at 14 weeks' gestation with an acute abdomen 1 week after first\u2010trimester screening (including NT measurement) performed elsewhere, which was negative for trisomies 21 and 18. Sonographic examination revealed an interstitial pregnancy with a singleton fetus with present cardiac activity, which had not been noted 1 week earlier at the time of earlier transabdominal NT measurement. This case indicates that successful acquisition of a NT measurement during first\u2010trimester screening for fetal aneuploidy does not negate the rare possibility of an unusual ectopic pregnancy. \u00a9 2008 Wiley Periodicals, Inc.
