Abstract: Deafness occasionally results from bilateral lesions of the temporal lobes. Conventional methods of assessing hearing are not helpful in the diagnosis of this condition. We describe the case of a patient who exhibited the hallmark of a cortical hearing disorder--he was able to hear simple sounds, but could not make sense of complex sounds such as speech and music.
