A Rare Presentation of a Brown Tumor on the Spinal Column Secondary to Chronic Renal Failure Managed by Dialysis

Abstract

A brown tumor (BT) is a rare tumor composed of giant cells, and is a complication seen in secondary hyperparathyroidism related to chronic renal failure. Mediated by osteoclastic bone resorption, increasing bone turnover leads to the formation of a multinucleated giant cell tumor, also known as osteitis fibrosa cystica or BT. A BT is usually located at, but not limited to, the mandible, long bones, pelvis, and ribs. We present a case of a 40-year-old female with a BT and a history of chronic renal failure managed by dialysis. A concurrent parathyroid adenoma was also found on imaging. A laminectomy of T8 and partial T7 - T9 fusion was completed, followed by a complete parathyroidectomy 10 days later. J Curr Surg. 2020;10(1-2):13-16 doi: https://doi.org/10.14740/jcs400
