Postma","Anouk Y. J. M. Smeets"],"abstract":"Background: Several case reports about spinal cord compression due to hyperostosis at the craniocervical junction are available. However, compression at C1-C2 solely due to ossification of the posterior longitudinal ligament (OPLL) is rare. Case Description: A 50-year-old Asian male, with a history of lumbar spinal canal stenosis, presented with a progressive quadriparesis within 3 months. Imaging showed central OPLL at the C1-C2 level contributing to severe spinal cord compression. The patient improved neurologically after a C1-C2 laminectomy. Conclusion: A patient presented with a progressive Brown-Séquard syndrome due to OPLL at the craniocervical junction (C1-C2 level) and improved following a decompressive laminectomy.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/ee349ae9-527f-4417-95f4-3fcbdef1a917/featured/hero-1781561962107.png","publishDate":"2021-10-06T00:00:00.000Z","doi":"10.25259/SNI_704_2021","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/ee349ae9-527f-4417-95f4-3fcbdef1a917/pdf"}
