 | Media file 1: Bilateral sacroiliitis. Frontal radiograph shows bilateral sacroiliac joint erosions and iliac side subchondral sclerosis. |
 | Media file 2: Bilateral chronic sacroiliitis. Frontal radiograph shows complete fusion of both sacroiliac joints. |
 | Media file 3: Romanus lesions. Lateral radiograph shows anterior corner erosions at the T12 and L1 vertebral bodies. The typical shiny corner sign (or Romanus lesion) is present (arrows). |
 | Media file 4: Vertebral body squaring. Lateral radiograph shows squaring of L3 and L4 vertebral bodies, L3-L4 anterior syndesmophyte, and lumbar facet joint fusion. |
 | Media file 5: Interspinous ossification. Frontal radiograph shows T12-L2 lateral syndesmophytes and interspinous ligament ossification extending from the T12 to L1 and L2 to L4 levels. |
 | Media file 6: Vertebral fusion. Lateral radiograph shows solid ankylosis of all cervical facet joints from C2 downwards. Extensive anterior and posterior syndesmophytes is noted. |
 | Media file 7: Bamboo spine. Frontal radiograph shows complete fusion of the vertebral bodies. Extensive facet joint ankylosis and posterior ligamentous ossification produce the trolley track appearance. |
 | Media file 8: Disk calcification. Lateral radiograph shows L2-L3 and L3-L4 disk calcifications, as well as L2-L4 anterior syndesmophytes. |
 | Media file 9: Thoracolumbar junction fracture. Lateral radiograph shows features of established ankylosing spondylitis. A T12 vertebral body fracture is noted, with disruption of the ossified anterior longitudinal ligament (arrow). An old L1 compression fracture is present. |
 | Media file 10: Chalk stick fracture. Lateral radiograph shows a fracture through the ankylosed cervical spine, producing a gap at the C6-C7 disk. |
 | Media file 11: Pseudoarthrosis. Lateral radiograph shows a T11-T12 diskovertebral lesion with adjacent sclerosis (Andersson lesion; arrow). Posterior element defect is present (arrowheads). The patient also has a severe kyphotic deformity. |
 | Media file 12: Pelvic enthesopathy. Frontal radiograph shows ill-defined erosions with adjacent sclerosis at the left ischial tuberosity and more established new bone formation on the right side. |
 | Media file 13: Shoulder enthesopathy. Frontal radiograph shows irregular bony proliferation at the coracoclavicular ligament attachment sites to the inferior clavicle and the superior coracoid process. |
 | Media file 14: Hip joint changes. Frontal radiograph shows uniform joint space narrowing and a collar of osteophytes at the femoral head-neck junction. Left sacroiliac joint ankylosis is present. |
 | Media file 15: Bilateral sacroiliitis. Axial CT scan shows erosions and iliac side subchondral sclerosis of both sacroiliac joints. |
 | Media file 16: Pseudoarthrosis. Reconstructed midsagittal CT image shows an L1-L2 diskovertebral lesion with adjacent sclerosis. |
 | Media file 17: Pseudoarthrosis (same patient as in Image above). Reconstructed posterior coronal CT image shows bilateral posterior element breaks (arrows). |
 | Media file 18: Bilateral facet joint ankylosis. Axial CT scan shows complete fusion of both T12-L1 facet joints. |
 | Media file 19: Dural ectasia. Axial postmyelographic CT scan shows prominent dural ectasia with scalloping of the adjacent vertebra. Partial fusion of the facet joints is noted. |
 | Media file 20: Pseudoarthrosis. Sagittal T1-weighted MRI shows a prominent T11-T12 diskovertebral lesion (arrows) with posterior element involvement (arrowheads). |
 | Media file 21: Pseudoarthrosis (same patient as in Image 20). Sagittal T2-weighted image shows the linear area of high signal intensity extending obliquely from the T11-T12 diskovertebral lesion (arrows) to the posterior elements (arrowheads). |
 | Media file 22: Quantitative scintigraphy. Increased sacroiliac joint uptake is seen, with a sacroiliac joint-to-sacral uptake ratio that exceeds 1.7:1 on each side. |
