Need for treatment : depends on size & location of arachnoid cysts & whether or not they cause neurological symptoms from pressure on underlying brain tissue. Neurosurgeons perform minimally invasive micro neurosurgical endoscopic procedures to remove membranes of a cyst or open a cyst so its fluid drains into the normally flowing cerebrospinal fluid.
