Syringomyelia resolution after anterior cervical discectomy: A case report and literature review

Abstract

Background: Syringomyelia is rarely associated with cervical disc herniations and/or spinal stenosis. Case Description: A 62-year-old male presented with a 4-month history of right brachial pain and hyposensitivity in the C5 distribution. The cervical magnetic resonance (MR) imaging scan revealed a C5–C6 right anterolateral disc herniation with syringomyelia extending from C5–C6 to T1. Following a C5–C6 anterior cervical discectomy and fusion (ACDF), the patient’s symptoms resolved. The 3-month postoperative MR documented total resolution of the syrinx. Notably, due to residual neuropathic pain, the patient required a subdural spinal cord stimulator which was placed without any complications. Conclusion: Syringomyelia rarely occurs in conjunction with cervical disc disease and stenosis, and even more infrequently resolves following an ACDF. Future research should focus on the etiology of syrinx formation in these patients and should explore their response to various treatment modalities.
