Arachnoid cyst is a congenital collection of fluid similar like cerebrospinal fluid between the leaves of arachnoid. Usually they have no connections with subarachnoid space. Symptomatic arachnoid cysts are treated surgically. The method of surgical treatment depends according to the cyst location, surgeons experience and available instruments. The methods of arachnoid cysts surgical treatment are: craniotomy and open cyst extirpation and connection with subarachnoid space, endoscopic cyst aspiration and connection with subarachnoid space (cystocysternostomy) or ventricles (cystoventriculostomy) and cystoperitoneal shunting. We describe the method of endoscopic treatment of arachnoid cysts and review the clinic, diagnostic and early results of patients treated at the Department of Neurosurgery, Klaipėda University Hospital. There were 6 patients who underwent endoscopic surgery for arachnoid cysts during the period from January 2011 till January 2013. Four patients (66.7 proc.) had arachnoid cysts of middle cranial fossa and two (33.3 proc.) had intraventricular arachnoid cysts. Four patients underwent endoscopic cystocysternostomy and two patients underwent endoscopic cystoventriculostomy and cystoventriculocysternostomy. We observed early improvement in all patients. Diabetes insipidus has developed to one patient as a complication of surgery. Conclusion. Endoscopic surgery for arachnoid cysts is an effective, safe and minimally invasive treatment method. It must be the first method of surgery for most symptomatic arachnoid cyst.
