Résumé
Alobar holopresencephaly is a rare embryonic condition where there is anomalous fusion of cerebral hemispheres. The key features include neurological impairment and facial dysmorphism like cyclopia, ocular hypertelorism with divided orbits and a proboscis. Obstetric ultrasound and foetal MRI are the diagnostic modalities. Majority of cases are sporadic in origin while a genetic association is also described. A small recurrence risk is noted in cases with sporadic origin. Early diagnosis and pregnancy termination are advisable for the condition since the survival rate is very low.
