Epilepsy is, above all, a pediatric disease. The electroclinical expression of epilepsy depends on several factors, including the presence of a subjacent brain anomaly and the age of the child. Genetic, congenital, and perinatal disorders account for most of the cases. MR imaging should identify any abnormality of the brain, in order to understand the condition and, in selected cases, to be able to treat the patient surgically.
