Summary
A rare retro-odontoid pseudotumor causing cervical myelopathy can be treated with C1-laminectomy. Surgical decompression, without tumor resection, improved the patient's neurological function and reduced the pseudotumor size.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Cervical myelopathy presents a diagnostic challenge, particularly with rare retro-odontoid lesions.
- Repetitive neck movements, such as those in long-term cycling, may contribute to the development of cervical spine conditions.
Observation:
- A 63-year-old male developed subacute myelopathy attributed to repeated neck axial movements from cycling.
- Cervical MRI revealed a retro-odontoid mass compressing the upper spinal cord.
Findings:
- Clinical diagnosis of a retro-odontoid pseudotumor was made after excluding malignancy and inflammatory conditions.
- Posterior C1-laminectomy without tumor resection led to neurological improvement and a mild reduction in pseudotumor size on follow-up MRI.
Implications:
- Neurophysicians should consider benign retro-odontoid pseudotumors in cervical myelopathy cases.
- Decompression surgery alone, without tumor resection, can be effective for managing these pseudotumors, potentially leading to size reduction.
