Abnormal subchondral bone marrow signal involving both surfaces of the sacroiliac joint and displays low signal on T1 and high signal on STIR images depicting an inflammatory process.
Joint space of both ligamentous and synovial parts of the joints is preserved.

The shape and signal intensities of the muscles attachments also are normal.
