Selected hearing impairment associated with pinealoma.
A 23-year-old Caucasian male entered the audiology clinic with a complaint of difficulty understanding speech, although speech sounds could be heard. Conventional clinical audiometry showed normal sensitivity bilaterally. The speech discrimination tests confirmed his inability to comprehend speech adequately. Békésy audiometer tests revealed dramatically rapid temporary threshold shifts bilaterally. Subsequent physical examinations revealed a massive pinealoma. Thirteen days after completion of Torkildsen's procedure, all the auditory tests indicated normal auditory function in each ear.
