Aortitis in a patient with psoriatic arthritis.

Aortitis, inflammation of the aortic tissue, is most commonly caused by vasculitic rheumatic conditions, and less frequently infectious organisms. Involvement of the aorta is well defined in HLA-B27-associated spondyloarthropathies such as long-standing ankylosing spondylitis and Reiter's syndrome. However, unlike other spondyloarthropathies, aortic involvement or true aortitis is not a feature of psoriatic arthritis and has been reported in only a few cases. Herein, we report the case of a 22 year-old woman with psoriatic arthritis who developed descending aortitis while using tumor necrosis factor inhibitors.
