Figure 4: (A-E): Tuberculous sacroiliac joint infection. Plain film of the left sacroiliac joint (A) shows large erosions with surrounding sclerosis on both sides of the left sacroiliac joint (black arrows). CT scan of the sacroiliac joints (B) confirms marked destruction of the left sacroiliac joint. Coronal fat-suppressed T1W MRI (C) shows a hyperintense peripheral rim around an intraosseous abscess within the left sacrum (arrows). Axial, contrast-enhanced, fat-suppressed T1W MRI (D) shows peripheral enhancement of the large subchondral erosions and adjacent intraosseous abscess. Note the enhancement of the synovium and of the soft tissues anterior to the left sacroiliac joint (asterisks). Coronal, contrast-enhanced, fat-suppressed T1W MRI (E) shows contrast uptake on both sides of the left sacroiliac joint, absence of contrast uptake within the central part of joint and multiple areas of contrast uptake within the sacrum and spine, due to associated disseminated tuberculous osteomyelitis
