Nevertheless, they should be considered among the differential diagnoses for spinal intradural/extramedullary lesions. Case Report: A 65-year-old male presented with progressive back pain and right S1 radiculopathy. Magnetic resonance imaging scan revealed a right-sided posterolateral intradural/extramedullary lesion at the L5–S1 level. It was hyperintense on T1 and hypointense on T2-weighted images; on the short TI inversion recovery sequence it was hyperintense. The lesion was excised through a right L5 hemilaminectomy, and the patient was neurologically intact postoperatively. Histopathology revealed a chronic subdural hematoma. Conclusion: Chronic spinal subdural hematoma can mimic intradural extramedullary spinal tumors even in the absence of trauma and/or coagulopathies.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/e90f2914-3ea2-4e2d-8388-fa863927bccf/featured/hero-1782420896313.png","publishDate":"2017-09-26T00:00:00.000Z","doi":"10.4103/sni.sni_262_17","categories":["Spine","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2017/10/8614/SNI-8-231.pdf"}
