Swelling and enhancement of the cervical spinal cord: when is a tumour not a tumour?

OBJECTIVE

To describe the management of patients with co-existing cervical spondylotic compression and enhancing intramedullary swelling of uncertain aetiology. We describe the key features, suggest a management plan and review the literature.

MATERIAL AND

METHODS

A short series of six cases with cervical myelopathy and radiological features of spondylotic compression, swollen cervical cord and intramedullary enhancement is described. Detailed descriptions of clinical features, radiological findings, surgical approaches and outcomes are discussed. All patients underwent cervical decompression via an anterior approach, posterior approach or both. Despite initial concerns that the aetiology might be tumour, no biopsy of cervical cord was required in any of the cases.

RESULTS

Symptoms improved in four cases whilst contrast enhancement only improved in two cases following decompression. One patient who failed to improve postoperatively was found to have neurosarcoidosis. No patient became worse after the cervical decompression.

CONCLUSION

Swelling of the spinal cord with enhancement and co-existing spondylotic cord compression, in the first instance, should be treated by decompression only. Biopsy to diagnose intrinsic tumour or inflammatory conditions should not be performed unless there is radiological or clinical progression despite adequate decompression.
