Magnetic resonance imaging of supratentorial congenital brain malformations.

The common supratentorial congenital malformations of the brain were analyzed with magnetic resonance (MR) at the Children's Memorial Hospital in Chicago over a two-year period. Three hundred children with one or more of the following congenital malformations were imaged with MR: (1) dysgenesis of the corpus callosum; (2) holoprosencephaly; (3) migrational disorders; (4) cephaloceles; and (5) septo-optic dysplasia. The characteristic findings in each of these disorders are described based on the MR scans as well as the clinical spectrum.
