Adult posterior fossa arachnoid cysts are rare lesions that are considered to be mostly congenital in origin. We present 49-year-old man admitted with a chief complaint of tremor and balance problems for the past 2 months. He had ataxia on examination. Magnetic resonance imaging revealed a well circumscribed midline cystic lesion of the posterior fossa sharing the same signal characteristics as cerebrospinal fluid and non-communicating to the fourth ventricle. He underwent surgical treatment for his symptomatic posterior fossa arachnoid cyst with a good outcome at 2 years follow up.
