How do the radiographic features of inflammatory sacroiliitis and spondylitis caused by postenteritic reactive arthritis differ from those in IBD patients?
Radiologic Comparison of Spinal Arthritis in Postenteritic Reactive Arthritis Versus Inflammatory Bowel Disease
| Reactive Arthritis | IBD | |
|---|---|---|
| Sacroiliitis | Unilateral, asymmetric | Bilateral, sacroiliac involvement |
| Spondylitis | Asymmetric, nonmarginal, jug-handle syndesmophytes | Bilateral, thin, marginal syndesmophytes |
IBD, Inflammatory bowel disease.
