Input: Abstract: Unilateral high pitched tinnitus was the sole epileptic ictal manifestation of a 45-year-old woman. Electrographic seizures originated from the contralateral midtemporal area and consistently correlated with tinnitus. Computed tomography (CT) demonstrated a lesion involving the superior temporal gyrus and inferior portion of the supramarginal gyrus. The case illustrates a cortical origin of tinnitus.
