A 25-year-old female suffered an attack of vertigo and noticed hearing impairment, so this case was initially treated as sudden deafness. Subsequently, she presented with facial nerve paresis and the diagnosis was found to be cerebellopontine angle meningioma after examination at another facility. Of tumors that occur in the cerebello-pontine angle, acoustic tumors have the highest frequency. Meningiomas occur in this part secondarily, and it is reported that they account for about ten percent of all tumors in this area. Cerebellopontine angle meningiomas cause vertigo and disequilibrium, but are rarely accompanied with sudden sensorineural hearing loss. When they develop as sudden deafness, it might be difficult to clinically differentiate meningioma and non-classic acoustic tumor. Meningiomas might therefore follow a rapid clinical course.
Key words :meningioma, vertigo attack, sudden deafness, facial palsy
