Introduction: Spinal extradural arachnoid cysts(SEAC) are a rare cause of spinal cord compression, nerve root compression, or both, accounting for approximately 1-3% of all primary spinal space-occupying lesions. Multiple SEACs are rarely reported in the literature. Aim of this article is to illustrate our experience of surgical treatment of this rare but curable disease.
Case Report: We present a case report of 15-year-old boy who presented with progressive lower extremity weakness, pain and dysaesthesia. Magnetic resonance (MR) of the spine revealed two extradural arachnoid cysts. The patient underwent a thoracic laminoplasty for en bloc resection of the spinal extradural arachnoid cyst. Postoperatively, the patient’s motor strength and ambulation improved immediately.
Conclusion: We have described a rare case of back pain and leg weakness in patient with multiple thoracolumbar spinal extradural cysts. Clinical outcome after Laminoplasty and surgical excision of cyst was excellent and there has not been any evidence of cyst recurrence and symptomatic worsening till now(three years post surgical enbloc excision).
