Figure 4 (A-E): Sacroiliitis on CT. (A) Oblique coronal CT scan in a 27 year old male with ankylosing spondylitis shows erosion on the left iliac articular surface (white arrow) with bilateral diffuse reduction of joint spaces and blurring of the articular cortex (black arrows). (B) Oblique coronal CT scan in a 49 year old female with ankylosing spondylitis shows bilateral reduction in joint space, erosions on both iliac side (thick black arrows) and sacral side (thin black arrows), along with bilateral subchondral sclerosis (white arrows). (C) Oblique coronal CT scan in a 24 year old male with inflammatory bowel disease shows multiple erosions (black arrows), subchondral sclerosis (white arrows), and widening of the joint space bilaterally. (D) Coronal oblique CT scan in another patient shows bony bridges on the right side (black arrow), subchondral sclerosis on iliac sides bilaterally (white arrows), and erosions in the left ilium (small white arrow). (E) Coronal oblique CT scan in a 65 year old male with ankylosing spondylitis shows complete ankylosis of both sacroiliac joints (black arrows)
