Abstract
|
|
|
Study Design : A case report.
Objectives : To report a case of spinal extradural arachnoid cyst.
Summary of Literature Review : Extradural arachonid cysts of the spine are a rare cause of spinal cord and nerve root compression. There are few reports about it, and the etiology remains unclear.
Materials and Methods : The authors performed a clinical and radiographic case review.
Results : A 56-year-old male patient presented with both lower extremity radiating pain and tingling sensation in both feet for four years. His MRI revealed a large, well-demarcated extradural lesion, isointense to cerebrospinal fluid from L1 to L3. We performed dural repair and laminectomy for partial resection of the cyst. The outcome was good in the immediate postoperative period, and the patient made a full recovery without complications.
Conclusions : Surgical treatment should be considered for large spinal extradural arachnoid cysts with neurologic symptoms when conservative treatment does not work.
