Overview
The term ankylosing is derived from the Greek word ankylos, meaning stiffening of a joint.CT allows direct visualization of the abnormalities in peripheral and axial joints. CT has resulted in a major improvement in the evaluation and management of patients with AS. Findings on CT scan suggestive of ankylosing spondylitis include erosion, osteoporosis / sclerosis, and new bone formation. However,CT has poor ability to detect soft-tissue changes and best in detecting osteoporosis or osteosclerosis.
CT scan
- Findings on CT scan suggestive of ankylosing spondylitis include:[1][2][3]
- Erosions
- Subchondral sclerosis
- Bony ankylosis
- Sacroiliitis
- Bamboo spine
- Ligamentous ossification and periarticular and intra-articular ankylosis
- Best in demonstrating injuries to the following:
- Cervical spine fracture especially in advanced ankylosing spondylitis patients
