Simple partial seizures with hemisensory phenomena and dysgeusia: an insular pattern

Abstract

Insular seizures are rarely described, in part owing to the complex anatomy of this brain region. We present a patient with simple partial seizures, recorded intracranially, originating in the right insula and characterized by dysgeusia and contralateral somatosensory phenomena. This rare clinical pattern seems to be characteristic of the insula and may be undetectable with surface EEG.
