Management of migrating spinal schwannomas: a surgeon's dilemma. Illustrative case.

Background: A migrating spinal tumor is a rare phenomenon in the medical literature. Efficient management of these tumors is critical to avoid extended laminectomies.

Observations: In this article, the authors present the case of a patient with a migrating lumbar schwannoma. They summarize a literature review of similar cases, highlighting the intraoperative challenges faced, and provide management guidelines for similar cases from their experience.

Lessons: Surgeons dealing with spinal intradural extramedullary lesions should always consider the possibility of tumor migration. Routine preoperative counseling regarding potential tumor migration and its efficient management is essential, as it reduces the risk of unplanned extensive laminectomy or durotomy, minimizing morbidity and medicolegal concerns and enhancing patient care.
