Despite the benign character, dissemination and metastasis have occasionally been reported. The retrograde dissemination to other levels of the neuraxis is extremely rare, being more frequent to the intracranial compartment. Case Description: We hereby present a case of medullary metastasis of cauda equina MPE, with a history of having undergone a subtotal resection and postoperative adjuvant radiotherapy. The patient presents complaints of night dorsal pain attributable to intradural metastasis twenty-one years after the first surgical intervention. Conclusion: The case reported highlights the importance of long follow-up in patients with MPE, since the possibility of secondary seeding to distant craniospinal sites or local spinal sites after surgery, and radiotherapy should be considered in metastatic disease. 2025-10-24T10:26:51Z 2025-10-24T10:26:51Z 2020-07-08T09:14:56Z 2020-07-08T09:14:56Z 2019-05-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://hdl.handle.net/11351/5070 Surgical Neurology International;10 https://surgicalneurologyint.com/surgicalint-articles/a-rare-case-of-an-intramedullary-metastasis-of-a-myxopapillary-ependymoma/# Attribution-NonCommercial 4.0 International http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Scientific Scholar Scientia
