A 50-year-old woman presented with a left lumbar paraspinal schwannoma, a benign nerve sheath tumor located deep in the retroperitoneal space. MRI revealed two well-defined lesions measuring 10 × 5 cm, extending from L2 to L5, with no intracanalicular extension. She successfully underwent excision of the tumor through a transperitoneal minimally invasive approach, which provided excellent visualization, precise dissection, and safe tumor removal.

Although retroperitoneal masses are often considered a relative contraindication for laparoscopic surgery, in this case the patient underwent safe paraspinal mass removal with no intraoperative complications, minimal blood loss, and faster recovery compared to conventional open surgery.

The postoperative course was uneventful; the patient recovered smoothly and was discharged on the 4th postoperative day without neurological deficits or perioperative complications.
