BACKGROUND: To discuss the presentation, diagnosis, management modalities and outcomes of the arachnoid cysts. EXPERIMENTAL DESIGN: Retrospective study with a mean follow-up period of 31 months (ranging between 9 months and 5 years). SETTING: Institutional practice (The Military Medical Faculty Hospital). Patients and the participants: 25 patients with arachnoid cysts treated surgically. INTERVENTION: Fenestration and drainage of the cyst into cisterns in 13 cases, cyst-peritoneal shunting in 8 cases and cyst excision in 4 cases. MEASURE: The arachnoid cysts were followed-up by Computed Tomography or/and Magnetic Resonance Imaging. RESULTS: The results are excellent in 21 cases, moderate in 2 cases and poor in 2 cases. CONCLUSIONS: Regardless of the procedure used for arachnoid cyst treatment, the outcomes are somewhat similar if the surgical indications and techniques are properly selected.
