Spinal arachnoid cyst

Preoperative, operative and postoperative radiological examinations and operative notes of 31 patients with spinal arachnoid cyst operated on during 2002–2009 at the Institute of Medical Sciences, Banaras Hindu University, were evaluated. Sixteen patients were male and 15 were female. All patients were managed surgically: extradural arachnoid cysts were managed by excision and intradural arachnoid cysts were managed by marsupialization. There was no recurrence in the 4 years of follow up.
