Differentiating between benign and less benign: epilepsy surgery in symptomatic frontal lobe epilepsy associated with benign focal epileptiform discharges of childhood.
Benign focal epileptiform discharges of childhood are a genetically determined electroencephalographic trait. Assessment of their clinical relevance in children with epilepsy may be difficult if imaging reveals a lesion congruent or incongruous with the focus of the benign focal epileptiform discharges of childhood. This article reports a boy with parietooccipital benign focal epileptiform discharges of childhood in whom videoelectroencephalography and magnetic resonance imaging disclosed symptomatic frontal lobe epilepsy. Surgical removal of a focal cortical dysplasia in the left frontal lobe yielded freedom from seizures and positive behavioral and cognitive development. Nocturnal benign focal epileptiform discharges of childhood persisted until puberty (follow-up, 50 months). Early diagnostic differentiation of idiopathic syndromes such as idiopathic benign focal epilepsy of childhood from symptomatic focal epilepsies with a potentially less benign course is important. In symptomatic frontal lobe epilepsy, epilepsy surgery may yield an excellent outcome despite the presence of concurrent benign focal epileptiform discharges of childhood.
