[Arachnoid cyst of cerebellar-pontine angle clinically mimicking Meniere's disease].
Arachnoid cysts represent about 1% of all intracranial space-occupying lesions. Usually they are located in the middle cranial fossa while their localization in the posterior fossa is uncommon and generally remain asymptomatic or those are non-specific. The case of a 51 years old female is reported who was diagnosed by IRM of a 4,5 x 2 cm arachnoid cyst, situated on the left cerebello-pontine angle, with tinnitus, hearing loss and vertigo that mimicked a Meniere's attack. We think thees benign tumors must be included in the differential diagnosis of Meniere's disease because they can be indistinguishable from it clinically.
