On antenatal ultrasound, there may be also evidence of polyhydramnios, a secondary feature due to impaired fetal swallowing. Fetal holoprosencephaly is often associated with multiple facial anomalies also. An antenatal ultrasound study, at 32 weeks pregnancy, raised the suspicion of a brain malformation, but it was suboptimal due to maternal habitus. Holoprosencephaly (HPE) is a severe brain malformation characterized by abnormal cleavage of the prosencephalon in the 5th gestational week. e aetiology of holoprosencephaly is unknown.

Indeed, 2 cases of holoprosencephaly in our series were detected in women originally requesting nuchal translucency screening. Abstract Holoprosencephaly (HPE) is a heterogeneous central nervous system (CNS) anomaly that results from a primary defect in induction and patterning of the rostral neural tube (basal forebrain), leading to varying degrees of incomplete separation of the cerebral hemispheres and facial anomalies. Holoprosencephaly (HPE) In this 28 slides ultrasound lecture you will learn: Definition of Holoprosencephaly (HPE).
