Abstract
A rare case of bilateral cerebellopontine angle (CPA) arachnoid cysts (ACs), accompanied by cerebellar tonsillar displacement toward the foramen magnum, is presented. A 45-year-old woman presented with progressive dysphagia, vertigo, and truncal ataxia. Magnetic resonance imaging revealed bilateral CPA ACs and cerebellar tonsillar displacement. The right CPA AC was excised via a suboccipital approach. Decompression of the foramen magnum and duraplasty were also performed. The case reported here is the first case of bilateral CPA ACs. Decompression of the foramen magnum and excision of the cyst resulted in complete relief of symptoms.
