Abstract

The video demonstrates an operative approach to a recurrent cervical anaplastic ependymoma. MYCN-amplified anaplastic ependymomas are locally aggressive, recurrent, and have a high risk of iatrogenic injury. In this case, the patient presented with local, aggressive tumor expansion, arachnoid adhesions, and pial invasion ventral to the spinal cord. Subcapsular decompression minimized cord retraction from a dorsal approach. Removal of the tumor capsule was guided by bipolar stimulation paired with neuromonitoring. Local gross-total resection was achieved, and the patient had a postoperative improvement in his neurological deficits and myelopathy.
