[Intracranial arachnoid cysts. Neuroendoscopic treatment]

The author reports the techniques and results of seven patients with intracranial arachnoid cysts treated surgically, all of them through neuroendoscopic approach. Two carriers of supraselar cysts had undergone several shunt surgeries, and another carrier of a temporal cyst undergone external drainage to treat an associated subdural higroma. Only in this case the endoscopic approach has not resulted in control of the symptoms of the patient. The follow up period extended from one to nine years.
