A diamniotic-monochorionic pregnancy of twins was revealed by transvaginal ultrasonography: one fetus with holoprosencephaly was diagnosed at 11 weeks of gestation. This is the first case of holoprosencephaly diagnosed in the first trimester. Prenatal diagnosis of this anomaly in the first trimester is now possible by transvaginal ultrasonography.

D016142 Holoprosencephaly Anterior midline brain, cranial, and facial malformations resulting from the failure of the embryonic prosencephalon to undergo segmentation and cleavage. Alobar prosencephaly is the most severe form and features anophthalmia; cyclopia; severe INTELLECTUAL DISABILITY; CLEFT LIP; CLEFT PALATE; SEIZURES; and microcephaly. Semilobar holoprosencepaly is characterized by hypotelorism, microphthalmia, coloboma, nasal malformations, and variable degrees of INTELLECTUAL DISABILITY. Lobar holoprosencephaly is associated with mild (or absent) facial malformations and intellectual abilities that range from mild INTELLECTUAL DISABILITY to normal. Holoprosencephaly is associated with CHROMOSOME ABNORMALITIES.
