Holoprosencephaly can be diagnosed even in the first trimester after 11–12 weeks.

Lobar Holoprosencephaly: Absent CSP present in 100% of cases. Diagnosis is then confirmed through magnetic resonance imaging (MRI) or a computed tomography (CT) scan. Genetic syndromes are found in 20% of cases. Classically three subtypes have been recognized, however additional entities are now included in the spectrum of the disease. Extracerebral defects are particularly common in fetuses with trisomies 13 and 18 and those with genetic syndromes. 2.

Holoprosencephaly (HPE) is a cephalic disorder in which the prosencephalon (the forebrain of the embryo) fails to develop into two hemispheres.Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy.The condition also occurs in other species. The fundamental problem is a failure of the developing brain to divide into left and right halves (which normally occurring at the end of the 5th week of gestation). Med Ultrason. Part A Clin. An MRI of the fetus, at 34 weeks pregnancy, demonstrated semilobar holoprosencephaly. Ultrasound diagnosis: Ultrasound diagnosis is made usually in the late second and third trimesters. Birth Defects Res. There was no family history of birth defects. On antenatal ultrasound, there may be also evidence of polyhydramnios, a secondary feature due to impaired fetal swallowing.

Winter TC, Kennedy AM, Woodward PJ. In alobar holoprosencephaly, the thalami are fused and there is a single large posteriorly located ventricle. Between 1990 and 2005, a collective of 51 fetuses with tentative ultrasound diagnosis of HPE was recruited at two tertiary referral centers for prenatal ultrasound diagnostics via the Pia Fetal Database (GE Medical Systems, Webling, Germany).
