Multiple intradural-extramedullary spinal ependymomas including tumors with different histological features.

Abstract

We report a rare case with multiple intradural-extramedullary spinal ependymomas with different histological features. A 26-year-old female presented to our hospital because of difficulty in walking due to progressive paresis. Magnetic resonance imaging of the thoracic spinal cord showed multiple spinal cord tumors. Surgical resection of these tumors was performed and a different histological diagnosis including World Health Organization Grade III anaplastic ependymoma and Grade II ependymoma was obtained using the resected specimen. Additional radiotherapy and chemotherapy were also performed, and a successful outcome has been maintained for at least 3 years after surgery. Surgical resections and subsequent radiotherapy and chemotherapy for cases with multiple intradural-extramedullary ependymomas can result in a good postoperative course.
