Case Description: A 49-year-old male acutely presented with an incomplete cauda equine syndrome. When the MRI showed a L4-L5 posterior extradural lesion that enhanced with gadolinium, an urgent left hemilaminectomy was performed. The lesion proved to be a sequestrated disc herniation rather than a tumor. Notably, postoperatively the patient almost completely recovered after 6-month follow-up. Conclusion: Even on contrast-enhanced MRI studies, posterior extradural sequestered lumbar disc herniations may mimic tumors.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/0eb4ef9e-cdb9-46c6-b80f-afc32dac4a2e/featured/hero-1781562382823.png","publishDate":"2021-06-07T00:00:00.000Z","doi":"10.25259/SNI_504_2021","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2021/06/10860/SNI-12-267.pdf"}
