Malignant migrating partial seizures in Aicardi syndrome.

This article reports on a female infant with Aicardi syndrome presenting with malignant migrating partial seizures from her first day of life. Initially, unilateral tonic seizures were seen with contralateral ictal electroencephalogram findings. Typically, these tonic seizures were accompanied by head and eye deviation and were followed by a tonic seizure on the other side of the body. At 6 months of age she developed epileptic spasms. She showed no motor development, did not respond to eye contact, and was nasogastric tube-fed. The epilepsy syndrome in this child is refractory to antiepileptic treatment and there is no psychomotor development. This case expands the phenotype of this catastrophic epileptic encephalopathy and suggests that the corpus callosum is not necessary for the 'migration' of partial seizures in this syndrome.
