Case Description: A 69-year-old male presented with a progressive parparesis/CES. When the magnetic resonance imaging revealed a T12-L1 epiconus/TL SC, a decompression was performed, resulting in symptomatic improvement (i.e., right-sided foot drop still resolving). Conclusion: ECS attributed to TL SC warrants immediate magnetic resonance evaluations and surgical decompression.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/7e1bc9fc-9afe-4c9f-a2f8-3d4b621999d0/featured/hero-1781558180882.png","publishDate":"2025-11-21T00:00:00.000Z","doi":"10.25259/SNI_1104_2025","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/7e1bc9fc-9afe-4c9f-a2f8-3d4b621999d0/pdf"}
