Gross total resection of benign retroperitonealy/intra/paraspinal giant schwannoma.

Schwannoma is a typically benign nerve sheath tumor. Here, a 30-year-old female underwent resection of a benign retroperitoneal/intra/paraspinal schwannoma. A 30-year-old female originally had urological surgery to remove an ill-defined retroperitoneal tumor. When she newly presented with right-side low back pain, and the magnetic resonance documented a recurrent/residual L1-L3 intra/paraspinal lesion, she required an additional tumor excision for the removal of the benign schwannoma. Spinal surgeons, dealing with benign schwannomas located in the retroperitoneal/intra/paraspinal compartments, need to work collaboratively with other surgeons (i.e., in this case, urologists) to achieve gross total tumor excision, and the best long-term results.
