Abstract

Schizencephaly (SchC) is the most frequent neuronal migration disorder consistent in a cerebrum spinal fluid–filled cleft, lined by gray matter. The clefts may extend through the hemisphere from the ependymal lining of the lateral ventricles to the pial surface of the hemisphere. The cleft can be uni- or bilateral and are commonly located near the pre- or postcentral gyry. It develops between the third and fifth gestational months. There are two types: closed-lip SchC, characterized by gray matter-lined lips that are in contact with each other (type 1), and open-lip SchC, which has separated lips and a cleft of CSF that is lined by gray matter and extending to the underlying ventricle (type 2). Prenatal imaging allows detection and characterization of open-lip Sch; there are no reported cases prenatally diagnosed of close-lip SchC. Additional abnormalities, such as polymicrogyria, gray matter heterotopia, absence of the septum pellucidum, may also be demonstrated.
