A 34-year old woman, hemodialized because of chronic renal failure, with secondary thyroid gland insufficiency, was admitted with lower limbs paresis, and underwent surgical removal of brown tumor of the sixth thoracic vertebra in 2011. The woman was admitted again in 2014 because of severe pain in the lumbar part of the vertebral column, with positive radicular signs on physical examination. An L4 tumor with severe stenosis of the vertebral canal and cauda equina compression were found on magnetic resonance imaging [Figure 1]. A brown tumor was diagnosed histopathologically, resembling the one from 2011.
|Figure 1: MR precontrast T2-weighted (a and c) images in the sagittal planes show inhomogeneous tumors, mainly of high signal intensity on T2, involving the spinous process of C6 (a) as well as the spinous process of L4 (c). CT scans with sagittal reconstruction (b and d) reveal expansive lytic lesions involving the vertebral body of C6 (b) and the vertebral body of L4 (d), respectively|

The brown tumor is a result of local increased osteoclastic activity during the course of parathyroid gland hyperactivity. It is most common in 40-year-old women in the thoracic part of the vertebral column and is rarely diagnosed as multifocal or recurrent.,
