Ependymoma of the Filum Terminale, Technical Operative Note

Background: Spinal cord tumors represent 2-4% of all CNS tumors. Ependymomas are the most frequent lesions spinal cord1. Gross total resection remains gold standard2. Method: We describe mini-invasive surgical technique using a fixed tubular retractor performed for an ependymoma filum terminale, along with its advantages and limits. Conclusion: This has shown to be safe effective terminale ependymoma, good impact on postoperative pain less risks CSF leak, which is probably secondary limited dead space.
