Abstract
|
|
|
An 82-year-old male patient was admitted for neck pain, motor weakness in both upper extremities, and gait disorder. The patient had no history of rheumatoid arthritis or other specific histories, and the findings of cervical myelopathy with retro-odontoid pseudotumor were confirmed by cervical magnetic resonance imaging. On cervical radiography, there was no evidence of atlantoaxial instability or subluxation.
Therefore, posterior fusion was not performed; only a C1 laminectomy was performed. Immediately after surgery, the pain decreased, and neurological symptoms were also improved. In the case of a retro-odontoid pseudotumor without atlantoaxial instability, it is believed that the symptoms can be improved only with C1 laminectomy.
