Malformations of cortical development are common neurological disorders characterized by disruptions in the normal development of cerebral gray and white matter during fetal life. We performed a quantitative, partly longitudinal investigation of cerebral volumes in a cohort of children with cortical malformations to investigate how their anatomical abnormalities change over time. Cortical malformation subjects showed volumetric curves that were comparable with those reported for healthy individuals, and reached peak cerebral volume, gray matter volume, and white matter volume at ages similar to those reported for healthy children. Volumes of heterotopic gray matter, however, demonstrated increases that were out of proportion to changes in cortical volume or caudate nucleus volume, suggesting that misplaced gray matter can have a unique pattern of maturation. Our findings demonstrate that overall brain growth in children with cortical malformations appears to mirror that of the healthy population, although malformed regions can show distinct growth patterns.
