Radiological Followup of the Evolution of Inflammatory Process in Sacroiliac Joint with Magnetic Resonance Imaging: A Case with Pyogenic Sacroiliitis
Figure 2
Contrast enhanced images on coronal MR planes through the sacroiliac joints on the first admission (0), and on follow-ups of 3rd, 6th and 12th months. Note the synovitis (arrow) and contrast enhancement indicating active inflammation in the subchondral bone (*). Contrast enhancement indicating synovitis has been diminished on the 3rd month and disappeared on the consecutive months as well as the bone marrow edema which is more pronounced in the first 3 months.
