Microsurgical resection of a giant cervico-medullary ependymoma: 2D-dimensional video.

Background: Ependymoma is a slowly growing benign neoplasm that constitutes 3-9% of all neuroepithelial spinal cord tumors.[3,4] They rarely involve the cervicomedullary junction where they both compress the distal brainstem and upper cervical cord. Due to the critical contiguous structures, gross total resection of these lesions may result in significant morbidity/mortality.
