An unusual cause of chronic neuropathic pain: report of a case of multiple intradural spinal arachnoid cysts and review of the literature

Abstract

Spinal arachnoid cysts (SACs) arise either intra- or extradurally and are usually solitary, while cases of multiple SACs have been scarcely reported in the literature. Herein, we report on a rare case of multiple and recurring intradural spinal arachnoid cysts (SACs) causing severe spinal cord compression and neuropathic radicular pain, in a 35-year-old female with a 10-year follow-up. Two separate attempts at surgery were performed but only provided temporary relief since the cysts recurred and new ones formed along the entirety of the spinal cord. Finally, a conservative approach with physiotherapy and a combination of analgesic medications was pursued.
