These lesions usually develop gradually and asymptomatic, however they can sometimes become symptomatic due to cyst expansion or intracystic hemorrhage. The current article explores a rare case of an arachnoid cysts of the middle fossa in a 36-year old male. The patient has been pleasing for 8 months an intracranial hypertension SD made of moderate headaches (VAS 6/10) associated with a bilateral blurred vision, complicated 4 months later by vomiting at the rate of one episode per day.
