Secondary spinal arachnoid cysts are challenging to manage, with iatrogenic factors, trauma, and hemorrhage being common causes. Surgical resection offers a lower recurrence risk than fenestration for intradural cysts.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Secondary spinal arachnoid cysts are rare and pose management challenges.
- They can be anteriorly located with extensive rostral-caudal extensions, often associated with arachnoiditis.
- Limited reports obscure disease features and optimal treatment strategies.
Conclusions:
- Secondary spinal arachnoid cysts, especially intradural ones, are difficult to treat with high recurrence rates after fenestration.
- Shunting procedures may be an alternative for unresectable cysts, but efficacy needs further data.
- Further research is needed to confirm the efficacy of shunting for secondary spinal arachnoid cysts.
