title: Facial spasm and paroxysmal tinnitus associated with an arachnoid cyst of the cerebellopontine angle--case report.
abstract: A 59-year-old female presented with a 3-year history of hemifacial spasm and paroxysmal tinnitus associated with an arachnoid cyst of the cerebellopontine angle, which was identified preoperatively by magnetic resonance imaging. Surgical decompression of the cyst and arterial decompression of the facial and acoustic nerves at their root exit zones resulted in complete resolution of the symptoms.
