Intermittent photic stimulation triggering a temporal lobe seizure in a patient with schizencephaly and pachygyria

Abstract

Photic stimulation is a common trigger for generalized epilepsies but may rarely incite focal seizures. Aside from documented cases of photosensitive occipital lobe epilepsies, few reported instances exist of focal epilepsies being triggered by intermittent photic stimulation. The case of a 12 year-old male with known schizencephaly, pachygyria, and right temporal lobe epilepsy triggered by photic stimulation is reported. To our knowledge, this is only the eighth reported case of photosensitive temporal lobe epilepsy.
