A case of holoprosencephaly and a little review

Abstract

Holoprosencephaly (HPE) is a birth defect that occurs during the first weeks of pregnancy and as a result the prosencephalon does not clearly divide in diencephalon, two halves of the telencephalon and lateral ventricles in the brain of the fetus and, in general, HPE is accompanied by facial defects. There are three main types of holoprosencephaly according to severity; alobar, semi-lobar and lobar. We report here a case that could be defined as a semi-lobar form of HPE with hydrocephalus and scarce facial malformations.
