Following the introduction of transvaginal sonography, several first trimester diagnoses of the exencephaly anencephaly sequence have been reported, with the earliest being described at 10 weeks of gestation. We report a case with a high index of suspicion for exencephaly at 9 weeks and 3 days because of three sonographic features: the cranial pole of the embryo was smaller than the chest, the cranial pole bulged dorsally and the surface of the cranium was irregular. The diagnosis was confirmed by a repeat ultrasound examination at 11 + 4 weeks and by autopsy after termination of pregnancy.
