Here, we present a patient with diffuse idiopathic skeletal hyperostosis (DISH) who developed a T10/T11 synovial cyst contributing to myelopathy that resolved following surgical cyst excision. Case Description: A 69-year-old male presented with progressive numbness and paraparesis for 2-month duration. The thoracic MR spine showed synovial cyst at the T10/T11 level, while the computed tomography confirmed DISH fusion between the T4 and T10 levels. Following a laminectomy with cyst excision, the patient’s symptoms resolved and he sustained no recurrent dynamic instability. Conclusion: A patient with DISH presented with the new onset of myelopathy attributed to a T10/T11 thoracic synovial cyst; following cyst excision, the patient’s myelopahty resolved.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/07023226-3e64-446a-9b64-eeb120a168a0/featured/hero-1781560915105.png","publishDate":"2022-09-30T00:00:00.000Z","doi":"10.25259/SNI_804_2022","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/09/11900/SNI-13-450.pdf"}
