Imaging of cervical spine involvement in inflammatory arthropathies: a review

Abstract

The cervical spine can be affected by many types of inflammatory arthropathies, and the most common autoimmune diseases with cervical spine involvement are rheumatoid arthritis (RA), spondyloarthritis (SpA), and juvenile idiopathic arthritis (JIA). The clinical symptoms of cervical spine pathologies are often nonspecific or absent; therefore, imaging plays a crucial diagnostic role. RA is the most prevalent autoimmune disease; it often leads to cervical spine instability and subsequent myelopathy. In SpA, due to new bone formation, the characteristic lesions include syndesmophytes, parasyndesmophytes, and bone ankylosis, but instabilities are rare. In JIA, early apophyseal bone ankylosis is characteristic, in addition to impaired spinal growth. The aim of this review article is to discuss the imaging pathologies found in patients with RA, SpA, and JIA in the early and advanced stages. This knowledge would be helpful in the proper diagnosis and treatment of these diseases.
