Surgical Approach of Cauda Equina Syndrome Secondary to L5 Lumbar Solitary Bone Plasmocytoma with Partial Resection and Lumbopelvic Fixation

Abstract

The solitary bone plasmacytoma is an uncommon cause of chronic lumbar pain. It belongs to a tumor group of plasmatic cells that usually disturbs the axial skeleton and can progress to multiple myeloma. The treatment of choice is radiotherapy; however, surgical management can also be done. Regardless of the no reliable data and little evidence, it is clear that the intervention is based on the classification systems of Enneking and Weinstein–Boriani–Biagini. This article will show a 66-year-old female patient with lumbar pain of 1 month with B symptoms. A solitary bone plasmacytoma diagnosis was made with pathology confirmation. A surgical procedure with improvement of symptoms was achieved, with 2 years of follow-up without relapse.
