Ankylosing spondylitis
Findings
Complete fusion of bilateral sacroiliac Joint. Mild flattening with irregularity, subcondral sclerosis and cyst noted involving right femoral head with reduced Right hip joint space Osteophytic changes involving lateral aspect of right femoral head
Discussion
Radiographic findings in sacroiliac joint reflect the sequence of inflammation, bone destruction and ossification. Three stages include 1. Pseudo widening of joint space 2. Erosive and sclerotic changes 3. Ankylosis. Radiographic changes in the hip joint include joint space narrowing, bone erosions, and new bone formation (osteophytes).
