A prolonged cerebrospinal fluid (CSF) leak is a known cause of SSCNS. We present a novel case where progressive SSCNS resulted from a chronic CSF leak related to an anterior cervical corpectomy.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 73-year-old man presented with gait ataxia and progressive hearing loss. Thirteen years before, he had undergone a combined anterior-posterior cervical decompression for symptomatic ossification of the posterior longitudinal ligament (OPLL). The presenting MR imaging showed extensive superficial siderosis and focal spinal cord herniation at the site of a ventral dural defect at the corpectomy site. A CT myelogram showed extensive CSF leakage into the corpectomy surgical site and a communicating pseudomeningocele in the anterior neck.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>This is the first reported case of progressive SSCNS as a long-term complication of an anterior cervical corpectomy for OPLL. Clinicians should be aware of SSCNS secondary to a chronic CSF leak in patients with a prior
