A Case of Rheumatoid Arthritis Presenting Initially as Atlantoaxial Subluxation / 대한류마티스학회지

ABSTRACT

We report here on a case of rheumatoid arthritis (RA) that progressed from the spine to the peripheral joints. In RA, the involvement of the cervical spine usually correlates with the progressive erosion of peripheral joints, such as the hand or foot, and the elevation of disease activity. Generally, it takes over 2 years of rheumatoid involvement of the cervical spine to cause laxity of the transverse ligament. The common types of rheumatoid cervical spine are anterior atlantoaxial subluxation, vertical subluxation and subaxial subluxation. We describe a 61-year-old woman with only neck pain initially. An MRI of the cervical spine showed atlantoaxial subluxation with features of the rheumatoid involvement. Arthritis later developed in both hands and symmetrically in other peripheral joints. She was diagnosed as having RA. This is the first case report of RA presenting initially as atlantoaxial subluxation.
