The rheumatoid inflammatory process can lead to pannus formation, bone destruction, and ligamentous laxity allowing at lantoaxial subluxation. Spinal cord and brainstem compression may cause neurological signs and symptoms. This reports on a patient in whom magnetic resonance imaging identified periodontoid pannus and atlantoaxial subluxation with spinal cord and medullary compression, manifested clinically by symptoms and signs consistent with cervical myelopathy. Posterior C1-2 fusion with atlantoaxial stabilization led to a reduction of pannus and neurological improvement.
