Epilepsia

Failure of anterior temporal lobectomy for temporal lobe epilepsy has raised the question of insular cortex involvement in these seizures. Because of difficulties in exploring the insula with invasive electroencephalography (EEG) recordings, only few studies have been performed and this question remains unanswered. ⋯ Insular involvement in temporal lobe seizure is not per se a prognostic factor for surgical outcome. Prognosis may be correlated with larger epileptogenic zones that our stereoelectroencephalography spatial sampling could have underestimated.
