Reversible audiological results in a patient with an extra-axial brain stem tumor

A case of a 32-yr-old patient with an extra-axial brain stem tumor is presented. Many postoperative audiological test results were reversed compared to the preoperative results. A variety of auditory measures were conducted to show which tests were sensitive to this patient's lesion. Also reported are some rather unique postoperative auditory changes which, in retrospect, provided an interesting view as to the extent of the lesion.
