Heterotopia are nodules or clumps of misplaced neurons that did not move to the correct location in the brain during earlydevelopment. Heterotopia are common malformations of cortical development.
Patients with subependymal heterotopias had a significantly higher prevalence of normal development than patients in the other two groups (P = .02). When all patients with gray matter heterotopias were considered, patients with thick heterotopias and those with overlying cortical gyral anomalies, which correlated with one another, had a significantly higher prevalence of developmental delay (P = .002).
