It is not feasible to comment on the need for surgery in absence of imaging review and history and physical exam. Most arachnoid cysts are lifelong and relatively benign. I would seriously doubt that it is causing your headaches, unless, you now have a mass effect causing increased intracranial pressure. Maybe, a virtual consult can help (www.connect@healthtap.com)
