Abstract

Arachnoid cysts are benign developmental collections of cerebrospinal fluid (CSF). They constitute approximately 1% of intracranial masses. The cerebellopontine angle (CPA) arachnoid cysts are rare and often asymptomatic. The onset of symptoms and signs is usually due to the compression of the brain, cranial nerves and obstruction of CSF circulation. The major clinical symptoms for CPA arachnoid cysts were reported as headache, ataxia and 8th cranial nerve palsy. We report a patient with a CPA arachnoid cyst. He presented with cranial nerve palsies and mirror movements found in upper extremities. We postulated that CPA arachnoid cyst compressing the brain stem and the pyramidal decussation may lead to mirror movements. We conclude that mirror movements can be associated with CPA arachnoid cyst.
