Large Paraspinal Schwannoma Removal via the Retroperitoneal Approach: A Case Report

Abstract

are found Schwannomas are benign tumors originating from the Schwann cells of the peripheral nerve sheath; these tumors usually occur in the head, neck, and extremities and account for almost 40% of extra-medullary tumors occurring in the human spine. The general consensus for the treatment of these tumors is gross total resection. However, due to differences in volume and the complex location involving both the spinal canal and the para-spinal area including the foramen, no consensus exists regarding the choice of a surgical approach. The classic surgical method is usually through the posterior or posterior-lateral approach. Here, we present a case of paraspinal schwannoma removed via the retroperitoneal approach.
