    Abstract Objective: To improve the diagnosis and treatment inspinal meningeal cysts(SMC). Methods: 14 cases of SMC were analyzed retrospectively.Low-back pain, sciatica, leg weakness, bowel and bladder disturbances are the symptomsmostly encountered. CT and MRI are decisive exam tools for SMC diagnosis. According to theexact location of the cysts, SMC can be categorized into: extradural, intradural andperineurial cyst (Tarlov cyst). Results: All of 14 cases were operated. The follow-upstudy revealed that 12 cases were normal neurologically and 2 improved. Conclusion:Surgical intervention is necessary if symptoms are getting worse progressively. The keypoints of operation are to close the ostium, resect the cyst wall and protect the nerveroots and/or spinal cord.
