Endoscopy for T10 nerve sheath tumor.

Minimally invasive surgery (MIS) is increasingly being adopted for spinal intradural tumors. Through the use of conventional microscopy or exoscopy for large lobulated nerve sheath tumors, the posterior root attachment is often visualized only after mobilizing the tumor. Here, the authors describe the utility of angled endoscopy with its panoramic view for a T10 nerve sheath tumor. Gross-total extracapsular excision was achieved utilizing a minimally invasive right paraspinous approach, fenestration, lateral durotomy, sliding delivery of the tumor, sharp dissection of radicular attachments under neuromonitoring, and dural closure with oblique clips. Angled endoscopes help visualize the attachments behind large multilobulated tumors and confirm the totality of excision.
