RESUMEN
Myxopapillary ependymoma in childhood typically occurs in the central nervous system. There are few surgical cases of myxopapillary ependymoma of the cauda equina in children. We report a case of myxopapillary ependymoma of the cauda equina in a 5-year-old boy, who presented with leg pain and abnormal gait. Subtotal resection surgery was performed. Following the subtotal tumor resection, follow-up magnetic resonance imaging evaluation showed a recurrent tumor. As a result, we performed a second subtotal tumor resection and followed with postoperative radiation therapy. No further evidence of the disease has been noted elsewhere in the patient in over ten years of follow-up. Myxopapillary ependymoma of the cauda equina in a young boy was improved by subtotal tumor resection and postoperative radiation therapy.
