Giant intradural myxopapillary ependymoma: review of literature.

This report presents the longest spanning intradural myxopapillary ependymoma consisting of 23 vertebral segments in the literature. An 11-year-old boy presented with right arm pain, mid back pain and progressive paraparesis associated with urinary retention. On MRI, the patient was found to have an intradural lesion extending from C5 to S3. The patient underwent T7 and T8 laminectomies with an almost total resection except for a minimal residual adhering to the spinal cord. The patient with the largest spanning spinal cord ependymoma was managed satisfactorily without significant morbidity. A small laminectomy may be used in some occasions despite the tumour's extensive size because it may have a single point of attachment to the cord.
