Laparoscopic resection of an incidental retroperitoneal schwannoma in a 74-year-old male: a case report and literature review

Background This case report highlights a rare retroperitoneal schwannoma in a 74-year-old male, discovered incidentally during a routine physical exam. Schwannomas in the retroperitoneum are uncommon and often present unique diagnostic and management challenges. Case summary The patient, a 74-year-old male with hypertension, presented with an incidental finding of a retroperitoneal mass (3.0 x 2.5 cm) on abdominal CT. Further imaging and histopathology confirmed a schwannoma. A laparoscopic resection was performed with no major complications, and the mass was confirmed to be benign with hemorrhagic and cystic degeneration. The patient recovered uneventfully post-surgery and was discharged with recommendations for long-term monitoring. Conclusion This case underscores the value of early detection through imaging and the effectiveness of minimally invasive surgery for retroperitoneal.
