Retroperitoneoscopic Resection of a Lumbosacral Plexus Schwannoma: Case Report and Literature Review

摘要

Background and Study Aims Schwannomas are benign tumors derived from the Schwann cells of the peripheral nerve sheath that rarely affect the retroperitoneum. When symptomatic, surgical resection is usually recommended via open surgery or the laparoscopic transperitoneal approach. We discuss the retroperitoneoscopic resection of lumbosacral plexus schwannomas through an illustrative case and literature review. A new management classification is also proposed.
