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 – subchondral edema and erosions. (A) Coronal STIR MR image in a 21 year old female with ankylosing spondylitis shows bilateral symmetrical edema in the subchondral and inferior aspects of the sacroiliac joints (white arrows). (B) Oblique coronal STIR MR image of the sacroiliac joint shows bilateral symmetrical edema in the posteroinferior aspect of the joints (white arrows). (C) Axial STIR MR image through sacroiliac joints shows multiple erosions (white arrows) with subchondral edema (black arrow)
