Ankylosing Spondylitis associated with Adult Still's Disease: The First Senegalese Case Report

Ankylosing spondylitis is the most common type of spondyloarthritis1, a group of diseases characterized by axial skeleton and sacroiliac involvement, peripheral joints and/or entheseal involvement and extra-articular manifestations1,2. Other types of spondyloarthritis are psoriatic arthritis, reactive arthritis, arthritis associated with cryptogenetic inflammatory bowel disease, S.A.P.H.O. (Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis), juvenile spondyloarthritis and undifferentiated forms. All other forms of spondyloarthritis can develop into ankylosing spondylitis1,2. This form, which can also occur at the outset, is characterized by the presence of sacroiliitis, often associated with stiffness and spinal deformities1,2,3.
