Psoriatic Spondylitis

Published Online:https://doi.org/10.1148/108.1.9

The radiographic findings of psoriatic spondylitis are described in 21 patients. The average age was 43 years and all patients but one were men. Nineteen had severe psoriasis and arthritis, with radiographic manifestations of arthritis especially involving the feet. Radiographic findings characteristic of psoriatic spondylitis include a high incidence of sacro-iliitis, usually bilaterally symmetric; a high incidence of coarse, asymmetrical syndesmophytes; atlanto-axial subluxation; and paravertebral ossification. Squaring of vertebral bodies and fusion of apophyseal joints were much less commonly observed than in ankylosing spondylitis.
