An Intramedullary subependymoma of the spinal cord is a rare tumor with only 43 reported cases in the literature. Most ofthem are reported to be localized within the cervical spinal cord. We report a rare case of a thoracic spine intramedullarysubependymoma in a 37-year-old female who presented with back pain and radiating leg pain. Subtotal resection and postoperativeradiotherapy were performed. Subependymomas developing in the spinal cord are benign with a low proliferativepotential. Complete resection of the tumor appears to be the optimal method for a complete cure. However aggressive surgerymay cause severe neurological deficit. Therefore, if severe neurological deficits are expected after complete removal, a partialremoval and postoperative radiation therapy is an alternative method for treatment in selected cases. A large-scale randomizedstudy is mandatory to clarify the effectiveness of radiotherapy and to establish the recurrence rate and prognosis with respectto the surgical removal of these tumors.
