Brief Summary

Schwannomas are benign tumors that can reach giant sizes. The diagnosis and treatment of these cases differ from those of small schwannomas. The aim of this study was to review the diagnoses and surgical approach characteristics of the giant spinal schwannomas (GSS) of patients who underwent surgery.
