Holoprosencephaly Alobar: A Case Report and Literature Review

Case Report Holoprosencephaly is a rare congenital brain malformation resulting from failure of diverticulation and cleavage of primitive prosencephalon which occurs at 4 8th week of gestation and is usually associated with multiple midline facial anomalies. It is the most common forebrain developmental anomaly in humans and a worldwide distribution. The etiology of HPE is very heterogeneous. Clinical expression is variable, extending from a small brain with a single cerebral ventricle and cyclopia to clinically unaffected carriers in familial holoprosencephaly. Here, we report neonatal case of holoprosencephaly alobar of premature girl 34t week, with microcephaly, flat nose, a single nostril, midline cleft lip palate and choanal atresia.
