Methods Seven patients from 1994 to 1999 were analyzed for their clinical and radiological findings. All or part of the cysts were resected + capsule neck ligation and microsurgical procedures were performed in 3 patients. Review the literature to explore the etiology and pathogenesis. Results Five cases were diagnosed preoperatively by CT or/and MRI. The MRI diagnosis rate was 10%. Excellent results were obtained in 7 cases, and 5 cases were followed up without recurrence. The time ranged from 4 months to 5 years. Conclusion MRI is a reliable method for diagnosing epidural cysts in the sacrum. Cyst resection and neck ligation are effective surgical methods. Those with severe adhesions should undergo microsurgery.
