Epidermoid cysts are slow-growing congenital tumors developed from ectodermal inclusions. They usually sit at the cerebellopontine angle or basal cistern, their location in the fourth ventricle are exceptional.We report the case of a 44-year-old patient admitted to the Neurosurgery department for chronic daily headaches with visual impairment recently aggravated by cerebellar stato-kinetic syndrome.The diagnosis of epidermoid cyst of the fourth ventricle was suspected on MRI especially in diffusion sequence and then confirmed by the anatomopatological studies. Subtotal surgical excision was performed. The evolution was marked by the disappearance of clinical signs. Radiological and clinical follow up were indicated.
