title: First-trimester diagnosis of exencephaly.
abstract: First-trimester diagnosis of fetal exencephaly is reported. Vaginal ultrasonography showed a normal volume of fetal brain with abnormal internal anatomy. The diagnosis was confirmed by repeat ultrasonography at 14 weeks and at subsequent termination of pregnancy. This is the earliest reported diagnosis of exencephaly by prenatal ultrasonography.
