Spinal cord ependymomas

Abstract

Ependymomas are the most common intramedullary spinal cord tumor in adults. With complete microsurgical resection, the recurrence rate of these tumors is very low. The strongest predictor of postoperative neurological function is preoperative disability. All intramedullary spinal cord tumors that may prove to be ependymomas should be approached with the goal of total resection. Intraoperative monitoring may help surgeons to preserve neurological function. Histological examination of the tumor intraoperatively may assist surgical decision-making, but it must be considered in the context of the gross appearance of the tumor, particularly the existence of a dissectable plane between the tumor and the spinal cord. If gross total resection is achieved, postoperative adjunctive therapy is unnecessary, and the patient should be followed radiographically for recurrence.
