Intradural extramedullary tumor location in the axial view affects the alert timing of intraoperative neurophysiologic monitoring
Authors' conclusion
Alert is probably triggered during tumor resection for anterolaterally located tumors. Alerts during tumor resection procedures were more likely to be rescued than other procedures in IDEM tumor surgery.
