A T1-weighted fat-suppressed gadolinium-enhanced MRI of the sacroiliac joints indicated joint space narrowing, bone erosions, subchondral sclerosis, and cortical irregularities in joint margins, indicating chronic damage and contrast agent uptake, both intra-articular and in the subchondral bone marrow, which is favorable for acute sacroiliitis (Figure 1).
