Most tumors are located in the mandible, pelvis, ribs, and large bones; only rarely is it found in the axial spine. Case Description: A 37-year-old male with primary hyperparathyroidism presented with an MR-documented T4 and T5 brown tumor (Osteitis Fibrosa Cystica) resulting in an acute paraparesis. The patient successfully underwent excisional biopsy of an expansile, enhancing, bony destructive lesion at the T4-5 level. Subsequently, he required subtotal excision of a left upper parathyroid tumor. Conclusion: Patient with primary hyperparathyroidism may acutely present with paraparesis attributed to brown tumors of the spine warranting emergent operative decompression.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/5a2bd01d-7b0f-468a-ab5d-7f5e379c802f/featured/hero-1781563055385.png","publishDate":"2020-10-21T00:00:00.000Z","doi":"10.25259/SNI_653_2020","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/5a2bd01d-7b0f-468a-ab5d-7f5e379c802f/pdf"}
