Objective To summarize the main points of diagnosis and treatment of epidural cysts in the orbit. 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.
