Alobar holoprosencephaly: A case report

Résumé

Introduction: Holoprosencephaly (HPE) is a rare brain malformation, which results from a cleavage defect of the prosencephalon. Three forms have been described as: alobar, semi-lobar, and lobar forms. Case Report: We report a rare case of holoprosencephaly, diagnosed at the maternity of the Ibn Rochd Hospital Center in Casablanca. Conclusion: Holoprosencephaly is secondary to a cleavage anomaly of the prosencephalon, the diagnosis is based on echotomography, computed tomography (CT) scan and nuclear magnetic resonance imaging (MRI). It is important to perform a karyotype to look for a chromosomal anomaly. Holoprosencephaly, although rare, should be recognized and diagnosed; minor forms are likely to benefit from medical replacement therapy or ventricular shunting.
