Seronegative spondyloarthropathy-related sacroiliitis: CT, MRI features and differentials.

Prakash D, Prabhu SM, Irodi A - Indian J Radiol Imaging (2014)

Bottom Line: Seronegative spondyloarthropathy is a group of chronic inflammatory rheumatic diseases that predominantly affect the axial skeleton.Involvement of sacroiliac joint is considered a hallmark for diagnosis of seronegative spondyloarthropathy and is usually the first manifestation of this condition.We present a pictorial essay of CT and MRI imaging findings in seronegative spondyloarthropathy-related sacroiliitis in various stages and highlight common differentials that need to be considered.

ABSTRACT
Seronegative spondyloarthropathy is a group of chronic inflammatory rheumatic diseases that predominantly affect the axial skeleton. Involvement of sacroiliac joint is considered a hallmark for diagnosis of seronegative spondyloarthropathy and is usually the first manifestation of this condition. It is essential for the radiologist to know the computed tomography (CT) and magnetic resonance imaging (MRI) features of spondyloarthropathy-related sacroiliitis as imaging plays an important role in diagnosis and evaluation of response to treatment. We present a pictorial essay of CT and MRI imaging findings in seronegative spondyloarthropathy-related sacroiliitis in various stages and highlight common differentials that need to be considered.

Findings of acute sacroiliitis on MRI - synovitis and marrow enhancement. Axial T1W fat-saturated (A) pre-contrast and (B) post-contrast MR images in a 52 year old female with psoriasis show enhancing joint synovium on the right side consistent with synovitis (white arrows); enhancement of anterior capsule is also seen (black arrow). (C) Coronal T1W fat-saturated post-contrast MR image shows subchondral bone marrow enhancement in the right iliac bone, findings consistent with active osteitis (white arrow)

(C) Coronal T1W fat-saturated post-contrast MR image shows subchondral bone marrow enhancement in the right iliac bone, findings consistent with active osteitis (white arrow)

Mentions: Subchondral bone marrow edema [Figure 6–8]: It is considered to be an earliest imaging sign of sacroiliitis and forms an important component of the ASAS criteria. It can be symmetrical or asymmetrical and typically involves lower and posterior portion of the joint surface
