Differences between pre- and postnatal diagnosis (new postnatal findings) are shown in bold

Cases of inharmonious development rather that of the real advantage of postnatal MRI over prenatal one are shown in italics

MMC myelomeningocele, CSF cerebrospinal fluid, CC corpus callosum, ACC agenesis of the corpus callosum
