Scientific background: Periventricular nodular heterotopia (PNH) that is one of the subgroups of neuronal migration disorders is associated with intractable epilepsy. However the etiopathogenesis of seizures in PNH patients are still unclear. Heterotopias are not involved in the epileptic network, alone. A complex relation between nodules, hippocampus and neocortex has been reported as the cause.
