Introduction: Holoprosencephaly occurs due to non cleavage of forebrain into two hemispheres in an embryo. It is a rare congenital disorder of brain which may be associated with facial dysmorphism. Holoprosencephaly is defect of gastrulation. It is mainly divided into three main types viz alobar, semilobar and lobar holoprosencephaly. It may be associated with midline facial defects like cebocephaly, ethmocephaly or cyclopia.
Case Report: 22 year old gravid 2 para 1 young female presented to obstetric clinical unit for general obstetric checkup. A routine sonogram for fetal well being was advised as she has not undergone any sonography during course of this pregnancy. Sonographic biometric parameters suggested gestational age of 30 weeks and 1 day. Fetal brain and face assessment revealed absent interhemispheric fissure, monoventricle, fused thalami and posterior fossa cyst in brain with reduced interorbital distance and mono nostril in face.
Discussion: Holoprosencephaly is a complex brain malformation affecting both forebrain and face. It is estimated to affect 1:16000 live births and 1: 250 conceptuses. Holoprosencephaly may be associated with midline facial anomalies like cebocephaly. Depending on the type of holoprosencephaly severity varies like alobar type are more severe followed by semilobar type.
Conclusion: Alobar holoprosencephaly has poor prognosis and may be associated with facial dysmorphism which further reduces chances of survival of fetus. Thus, early detection by prenatal ultrasound examination is important for proper management which not only help in avoiding additional burden on physical health of pregnant female but also prevents mental constrains if diagnosed early.
