saved Adobe InDesign 6.0 / /metadata Adobe InDesign 6.0 Schizencephaly is a rare cortical malformation that manifests as a grey matter-lined cleft extending from the ependyma to the pia matter The cleft extends across the entire cerebral hemisphere, from the ventricular surface (ependyma) to the periphery (pial surface) of the brain The early embryonic occurrence may be even higher but may not be detected due to most fetuses aborting in early gestation. People of any age can develop hydrocephalus and therefore require a VP shunt.
