Abstract:

PHYSICAL EXAMINATION:the blood pressure was 150/90 mm Hg, the tympanic membranes in both ears were complete and otopiesis. Audiogram showed total deafness in the right ear and slight sensorineural deafness at speech frequency and 80 db for high tone air conduction and 70 db for bone conduction at high frequency in left ear. Tympanogram showed "A" type in both ears and the ipsilateral and contralateral acoustic reflex in both ears were not induced. BAEP showed that the V wave threshold on the right was not induced and it was 50 dbnHL on the left. CT showed a limited low density area in the clivus. MRI showed a space-occupying lesion behind the basilar clivus and ahead of brain stem. Pathological examination showed CK(+), EMA(+), S-100(+) according to immunohistochemistry, which was in accordance with chondroid chordoma.
