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

Spinal arachnoid cysts (SACs) are rare occurrences that have been classified as part of the larger group of meningeal pathologies called spinal meningeal cysts. This report is, to the best of our knowledge, the first to describe the long-term outcomes in a patient with multiple de novo forming and recurring intradural SACs. The patient developed several cysts extending intradurally from the posterior fossa to the lower thoracic levels. The etiology of the condition could not be defined.

• 1
  Multiple intradural SACs are rare, with only six cases being reported in the literature, including the one hereby presented.
• 2
  Cyst recurrence may be rapid, and it is important to consider conservative management strategies upon failure of other invasive approaches, especially in the absence of severe symptoms.
• 3
  The patient's intradural SACs were conservatively managed during 3 years before surgical treatment.
