Abstract
- Arachnoid cysts compose 1% of all intracranial tumors and are usually incidental findings in brain imaging. They may present with symptoms such as dizziness, tinnitus and hearing loss, although they may be usually asymptomatic. In particular, presentation with sudden deafness is very rare. We report a case of a 21-year-old male who presented with sudden hearing loss linked to a cerebellopontine angle (CPA) arachnoid cyst. In this case, the cystic lesion at the CPA was found by magnetic resonance imaging of the brain. The hearing loss of this patient was successfully treated with steroids.
