 Ependymoma is the most common primary intramedullary tumor of the spinal cord, accounting for a quarter of these tumors. We experienced a case of ‘ependymoma of the spinal cord with a cystic lesion that presented as an intradural extramedullary tumor extending from the thoracic to lumbar vertebrae. In review of past literature on reports of spinal intradural extramedullary ependymoma, lesions spanning three or more vertebrae with cystic lesions were frequent, and about half were World Health Organization grade Ⅱ or higher. Dissemination or recurrence of these tumors may occur after surgery. There is no consensus on postoperative adjuvant therapy for intradural extramedullary spinal ependymoma, but careful consideration should be given to the intraoperative findings and the characteristics of the tumor.
