Most reports describe such cysts as communicating with the intrathecal subarachnoid space through a small defect in the dura. Excision of the cyst with obliteration of the communicating dural defect is the mainstay of treatment in symptomatic patients. Solitary extradural arachnoid cysts have been reported in several studies, but multiple extradural arachnoid cysts are very rarely reported in children. Materials and methods: The authors report a case of multiple extradural spinal arachnoid cysts in a 14-year-old boy who presented progressive lower extremity weakness, myelopathy, and severe gait ataxia. Magnetic resonance (MR) of the spine demonstrated four extradural arachnoid cysts extending from T-1 to T-9. The patient underwent a thoracic laminoplasty for en bloc resection of the spinal extradural arachnoid cysts. Postoperatively, the patient's motor strength and ambulation improved immediately. Conclusions: Multiple spinal extradural arachnoid cysts are rarely reported in the literature. Excision of the cysts at the spinal cord level leads to a favorable outcome.
