Bilateral and independent Broca areas confirmed by Wada test and functional magnetic resonance imaging.
Accurate preoperative evaluation of language dominance is critical when evaluating potential patients for temporal lobe epilepsy surgery. Although most people have left-sided language dominance, a minority of patients have been described with either bilateral or right hemispheric dominance. We present a patient with right temporal lobe epilepsy who presented with bilateral and functionally independent Broca areas, as confirmed by Wada testing and functional magnetic resonance imaging.
