Sacroiliitis (differential)
Magnetic
resonance images of sacroiliac joints: psoriatic arthritis. Shown are T1-weighted semi-coronal magnetic resonance images through the sacroiliac joints (a) before and (b) after intravenous contrast injection. Enhancement is seen at the right sacroiliac joint (arrow), indicating active sacroiliitis.
SAPHO
syndrome: the supposed trigger by isotretinoin, the efficacy of adalimumab and the specter of depressive disorder: a case report. MRI STIR images of lumbar osteitis and sacroiliac involvement before (upside) and after ADA treatment (downside)
SAPHO
syndrome with pathological fractures of vertebral bodies: a case report. Axial MRI scans of the sacroiliac joints illustrated inflammatory bone changes at the right sacroiliac joint that were hypointense on the T1-weighted image (a) and hyperintense on the T2-weighted image (b)
Extrapulmonary
tuberculosıs: an old but resurgent problem. Pelvic x-ray of a 46-year-old male. The late finding of tuberculous sacroiliitis is characterized by degenerative changes in the left sacroiliac joint (arrows)
Extrapulmonary
tuberculosıs: an old but resurgent problem. MR images of a 43-year-old male. Pre-contrast T1 weighted (a) and post-contrast (b) T1 weighted images demonstrate contrast enhancement in the synovium of the left sacroiliac joint in keeping with acute sacroiliitis (arrows). Arrowhead shows an abscess formation in the left iliac muscle that enhances peripherally after contrast injection
Ankylosing
spondylitis • Sacroiliitis - grade III - Ganzer Fall bei Radiopaedia
Teenager with
low back pain. Axial (above left) and coronal (above right) STIR MRI without contrast of the sacroiliac joints shows a linear area of bright signal in the left iliac bone just lateral to the left sacroiliac joint. Axial (below left) and coronal (below right) T1 MRI with contrast shows enhancement in the same area.The diagnosis was left sacroiliitis.
Sacroiliitis (inflammation of the sacroiliac joint) can be a manifestation of a wide range of disease processes. The pattern of involvement is helpful for narrowing down the differential diagnosis.
Usually bilateral and symmetrical
- enteropathic arthritis
- ankylosing spondylitis
- rheumatoid arthritis
- multicentric reticulohistiocytosis
- Whipple disease
Usually bilateral but asymmetrical
- gout
- psoriatic arthritis
- reactive arthritis (Reiter syndrome)
- osteoarthritis
- relapsing polychondritis
- Behcet disease
Usually unilateral
- neoplastic destructive process
- infective
- pyogenic septic arthritis
- tuberculous sacroiliitis
- brucellosis
- paraplegia
- SAPHO syndrome
Differential diagnosis
The following conditions can mimic a sacroiliitis
- hyperparathyroidism: not a true sacroiliitis but can mimic appearances
- osteitis condensans ilii
