Background: Intracranial arachnoid cyst (IAC) is a benign cystic lesion filled with cerebrospinal fluid (CSF). Different surgical treatments were evaluated to determine the most effective technique among several. Materials and Methods: A consecutive series of 68 adult patients (43 males, mean age 30.3 years, range 18-42 years) with IAC were surgically treated between January 2004 and January 2011. The cysts were supratentorial in location in 53 and infratentorial in 15 patients. Symptoms at presentation, location of the IAC, surgical treatment modalities, and postoperative complications were evaluated. Results: Of the 51 patients with headache, 44 (86.27%) patients had complete relief of the headache, five (9.80%) patients had significant improvement, and two (3.92%) had no worthwhile change. Three of the four patients with hydrocephalus and gait disturbances had relief of the symptoms and one patient had significant improvement. Of the five patients with cognitive decline and weakness, three (60.00%) patients showed improvement, and two (40.00%) patients had no significant change. Five (62.50%) of the eight patients with epilepsy had seizure remission, two (25.00%) patients had non-disabling seizures, and one had no change. Follow-up computed tomography (CT) scans showed variable change in the mass effect of IAC in 68 patients; cystic size was significantly reduced in 51 patients, no significant change in two patients of supratentorial arachnoid cysts. Cystic size was reduced in seven patients, but no significant change was observed in eight patients of infratentorial cysts. Three patients with enlarged head circumference had no further increase in the head circumference. Conclusion: Adult patients with IAC symptoms should be treated efficiently. Surgical treatment is associated with significant improvement in the symptoms and signs.
