A 31-year-old man visited us complaining of hearing loss and right ear tinnitus. Pure tone audiometry showed moderate sensorineural hearing loss with poor speech discrimination. Ear X-ray was normal. ABR revealed no response except wave-I. MRI clearly demonstrated a spaceoccupying lesion in the right cerebello-pontine angle ; it showed a low intensity signal in the Ti-weighted picture and a high intensity signal in the gadoliniumenhanced picture.A posterior fossa craniotomy revealed a partially cystic tumor arising from the ninth cranial nerve. Subtotal removal of the tumor was performed, leaving the 10th, 11th and 12th cranial nerves intact. After operation, pure tone audiometry and ABR results became normal.
