Spine involvement is less common in Reiter's syndrome than in other seronegative spondyloarthropathies. Also, cervical spine involvement rarely occurs in Reiter's syndrome and other spondyloarthropathies. This paper reports a rare case of Reiter's syndrome in which there was cervical spine involvement that presented clinically as an atlanto-axial rotatory subluxation. Reiter's Syndrome (RS) is one of the most common types of seronegative spondyloarthropathies (SSAs) that presents clinically with a triad of symptoms, i.e., conjunctivitis, urethritis, and arthritis. This case highlighted the importance of radiographs of the lateral cervical spine and dynamic cervical imaging for all patients who have Reiter's syndrome with cervical spine symptoms to ensure that this dangerous abnormality is not overlooked.
