Resection of intradural intramedullary subependymoma of the cervicothoracic spine: 2-dimensional operative video.

This video presents the case of a 44-year-old male with a 2-year history of pain in the left upper extremity that had worsened over the course of the last 6 months with associated weakened grip strength and had extended into his right arm. T2-weighted sagittal and axial MRI demonstrated an expansive nonenhancing solid intramedullary lesion extending from C5 to T1. The patient underwent a C5-T1 laminectomy and laminoplasty with near-complete resection of the intradural intramedullary subependymoma. At 3 months' follow-up, he reported doing well and had experienced significant improvement in motor strength with ongoing therapies.
