case_images: (a) Ankylosing change on the spinal X-ray with ivory vertebrae and syndesmophytes on multiple levels. Cortical erosion and hyperostosis of the vertebral bodies with bony bridging were also noted. In addition, sternocostoclavicular hyperostosis with obviously localized enlargement and clavicular osteosclerosis were found. (b) Coronal computerized tomography image showed obviously enlarged sternoclavicular joints with marked erosion, hyperostosis, and osteosclerosis. Cortical erosions and local hyperostosis were noted on the thoracic vertebra. (c) Axial computerized tomography images of the sacroiliac joints showing marginal erosions, profuse sclerosis at the iliac side of the right sacroiliac joint and ankylosing fusion on the left sacroiliac joint.

case_images: C-reactive protein at 20 ng/ml; erythrocyte sediment rate rose to 50 mm/h; spinal X-ray demonstrated wide-spread osteosclerosis, vertebral erosion, and multilevel bony bridging formation and marginal syndesmophytes [Figure 1a]. Chest computerized tomography (CT) revealed fusing destruction of her sternocostoclavicular joints with obvious hyperostosis [Figure 1b]. Pelvic CT showed obvious joint space narrowing, osteosclerosis and erosion of bilateral sacroiliac joints [Figure 1c].
