Surgical Resection of Cervical Meningioma: 3-Dimensional Operative Video

Spinal cord meningiomas are rare, benign lesions typically found at the cervical or thoracic spinal region. They can cause symptoms through compression of the spinal cord and nerve roots. These tumors often have a challenging surgical course due to their location in relation to spinal cord and nerve rootlets. We present a 33-yr-old female who presented with cervical radicular and myelopathy symptoms. MRI of the cervical spinal demonstrated an anterolateral, 3 cm intradural, extrameduallary tumor causing significant cord compression at C6-7 level. The patient was taken to surgery for cervical laminoplasty and microsurgical tumor removal. The current 3-dimensional video demonstrates the steps involved during the microsurgical resection of the tumor. In order to facilitate spinal cord rotation without compromising blood supply the dentate ligaments at 3 levels (C5-C7) were identified and transected, the anterolateral-situated tumor was separated from the exiting right C6 and C7 nerve rootlet followed by circumferential dissection, and subsequent en bloc resection. No complications were encountered during the procedure; somatosensory and motor evoked potential registration remained intact. The patient recovered well from the procedure and was discharged on postoperative day three with improvement in her presenting symptoms.
