Introduction: Cervical spondylotic myelopathy is one of the most common causes of cervical spinal cord dysfunction. Case Report: A 65-year-old patient was admitted with slowly-progressing myelopathic symptoms. Imaging studies indicated a massive lesion, which was thought to be a primary bone tumor. Resection at Segment C4 was performed, and histopathology showed hypertrophic facet joint. Discussion: Age-related degenerative changes and adaptation mechanisms result in hypertrophy of the joint and synovial cyst formation. In our case, it was enormous, and could be easily mistaken for a tumorous process. Conclusion: Such extensive hypertrophic changes are rarely addressed in the literature and should be considered as differential diagnosis.
