The unusual trajectory of the anterior cerebral artery that runs under the frontal bone is a new prenatal ultrasound marker which can be used together with the classic ultrasound markers and may be especially useful in diagnosing cases of lobar holoprosencephaly. Alobar and lobar holoprosencephaly are associated with microcephaly and midfacial defects in 80% of cases. Holoprosencephaly is a severe brain anomaly characterized by different degrees of fusion of the lateral ventricles resulting from failure of the prosencephalon to cleave during early embryogenesis.

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. Lobar holoprosencephaly. For more details see the article on lobar holoprosencephaly. 4. The prognosis is uncertain. Invasive testing for karyotyping and array. As with all types of holoprosencephaly, it is a rare congenital brain malformation in which there is failure of complete separation of the two hemispheres (which usually occurs around the 4th to 6th gestational weeks) and failure of transverse cleavage into the diencephalon and telencephalon.

Our case was lobar type of HP diagnosed on cranial ultrasound and confirmed by MRI examination. A wide spectrum of anatomical variants are characterized by a lack of midline separation of the cerebral hemispheres. Lobar holoprosencephaly is amenable to prenatal ultrasound diagnosis, although a differentiation with other cerebral malformations may be difficult at times. Aim: Holoprosencephaly (HPE) is the most common brain malformation. Holoprosencephaly is a rare spectrum of cerebral and facial malformations resulting from incomplete division of the embryonic forebrain (prosencephalon) into distinct lateral cerebral hemisphere.

Semilobar holoprosencephaly is a subtype of holoprosencephaly characterised by incomplete forebrain division. Holoprosencephaly may be associated to other midline defects and may be part of an aneuploidy such a trisomy 13 (Patau's syndrome).
