Dyspnea Caused by Atlantoaxial Subluxation in a Patient with Rheumatoid Arthritis

Atlantoaxial subluxation is a well-known but poorly recognized disease in rheumatoid patients. We report a patient with rheumatoid arthritis whose chief complaint was dyspnea on arrival to the emergency department (ED). After further investigation, spinal cord compression caused by atlantoaxial subluxation was diagnosed. This is an uncommon but important case that ED physicians should be aware of.
