ANAPLASTIC EPENDYMOMA OF THE SPINAL CORD

Abstract
An intraspinal ependymoma with cytological signs of malignancy and unusual further development was diagnosed in a 12 yr old boy. Only partial removal was possible; postoperative 60Co treatment was given. Ascending tumor growth was evident clinically in the spinal canal; 3 mo. later signs of intracranial extension of the tumor developed. The patients died 6 1/2 yr after the onset. Autopsy showed an anaplastic ependymoma with extensive intraspinal and intracranial growth. No other neoplasms were found. There was extraspinal extension of tumor into the laminectomy scar, but no metastases.
