“…The changes (eg, Romanus and Andersson lesions) seen in the diskovertebral unit have typical MR imaging appearances at different stages of spondyloarthritis. Three classes of lesions can be differentiated: acute inflammatory lesions, postinflammatory fatty bone marrow degeneration, and ankylosis (23). The typical MR imaging characteristics are summarized in the Table, which is provided as a guide to understanding the signalintensity changes seen during the course of ankylosing spondylitis.…”

Since the advent of highly effective TNF-alpha inhibitors for treating spondyloarthritides, referring rheumatologists have been requesting the sensitive visualization of inflammatory changes not only of the sacroiliac joints but of the entire spine. Given that changes in spondyloarthritis may be very subtle, their visualization by means of magnetic resonance (MR) imaging relies critically on selecting the proper imaging protocol. Spinal changes associated with spondyloarthritis are florid anterior spondylitis (or Romanus lesion), florid diskitis (or Andersson lesion), ankylosis, insufficiency fractures of the ankylosed spine, syndesmophytes, arthritis of the apophyseal and costovertebral joints, and enthesitis of the interspinal ligaments. A comparison of MR imaging findings with those of conventional radiography in individual patients reveals strengths and weaknesses of both modalities. Results of this comparison suggest that syndesmophytes are depicted better with radiography; ankylosis, equally well with both imaging techniques; and all other lesions, better with MR imaging. Classification of the different findings based on the typical signal-intensity changes seen on MR images enables standardized reporting, and scoring the lesions may be helpful in clinical trials.

Entheses are sites where tendons, ligaments, joint capsules, or fasciae attach to bone. Their function is to provide a mechanism for reducing stress at the bony interface by dissipating the biomechanical load acting on the bone. Enthesitis may occur in traumatic, endocrinologic, metabolic, degenerative, or inflammatory conditions and is a major symptom in patients with seronegative spondyloarthritis (SpA). The increasing interest in inflammation of the entheses associated with rheumatoid diseases has fundamentally changed our understanding of the clinical presentation, pathogenesis, and therapy of enthesitis. Conventional radiographs and computed tomography (CT) allow good evaluation of chronic changes of the entheses, such as soft-tissue calcification, erosions, and new bone formation. The method of first choice to evaluate acute enthesitis is magnetic resonance imaging (MRI), which depicts both soft-tissue changes and intraosseous abnormalities. The purpose of this overview is to discuss the MRI appearance of enthesitis in patients with SpA and to provide a morphologic survey of the predominantly affected entheses.
