An unusual cause of chronic neuropathic pain: report of a case of multiple intradural spinal arachnoid cysts and review of the literature
Formation of multiple intradural extramedullary cysts compressing the spinal cord at cervical and thoracic levels, with de novo cyst formation and recurrence after surgery
Target Population
Adults presenting with progressive neuropathic pain and neurological deficits related to spinal arachnoid cysts
Care Setting
Neurosurgical department with MRI imaging and surgical intervention capabilities
Key Highlights
Multiple intradural spinal arachnoid cysts are rare and can recur or form de novo over time.
Surgical excision can relieve spinal cord compression and improve symptoms but recurrence rates exist (~9.5-13%).
Conservative management with analgesics may be appropriate when cysts recur but symptoms remain mild.
Guideline-Based Recommendations
Diagnosis
Use MRI to identify cyst location, size, and spinal cord compression; cysts appear as high T2 signal and slightly higher T1 signal than CSF without contrast enhancement.
Perform detailed neurological examination focusing on dermatomal pain and motor weakness.
Management
Adopt a stepwise surgical approach targeting cysts causing the most severe spinal cord compression first.
Perform laminectomy with microsurgical cyst excision ensuring watertight dura closure.
Consider conservative management with analgesics if cysts recur but symptoms are mild.
Monitoring & Follow-up
Schedule regular clinical and MRI follow-ups post-surgery to monitor for cyst recurrence or new cyst formation.
Adjust management based on symptom progression and imaging findings.
Risks
Potential for cyst recurrence or de novo cyst formation despite surgical excision.
Progressive spinal cord compression may lead to neurological deterioration if untreated.
Patient & Prescribing Data
Adult patients with multiple intradural spinal arachnoid cysts presenting with neuropathic pain and spinal cord compression
Surgical excision improves symptoms and spinal cord compression; analgesic medications can be used for symptom control in recurrent or stable cysts without severe symptoms.
Clinical Best Practices
Obtain informed consent and use imaging guidance for precise surgical planning.
Use microsurgical techniques to completely excise cysts and achieve watertight dura closure to reduce recurrence risk.
Implement a staged surgical approach addressing the most symptomatic cysts first.
Maintain long-term follow-up with MRI and clinical assessment due to potential for cyst recurrence and de novo formation.
Consider conservative management when cyst burden increases but symptoms remain mild.
