Currently, endoscopic surgery to break up arachnoid cysts of cerebrospinal fluid is the most important treatment method. This surgical method is minimally invasive and effective because people use endoscopy to open the cyst wall to communicate with the subarachnoid space, or with the ventricles.

Arachnoiditis and cysts are relatively rare diseases. They can cause increased intracranial pressure, epilepsy, coma, convulsions, behavioral changes, loss of balance, cognitive impairment, etc.
