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.

Associated findings in seronegative spondyloarthropathy-related sacroiliitis on MRI. (A) Axial STIR MR image at L5-S1 shows left facetal joint subchondral edema (white arrows). (B) Coronal STIR MR image through both hip joints shows edema at tendinous insertion in the right greater tuberosity of femur, suggestive of enthesopathy (white arrow). (C) Coronal STIR MR image through both hip joints shows minimal joint effusion with prominent synovial thickening indicating synovitis (white arrows). (D) Sagittal T1W MR image of lumbosacral spine shows bridging syndesmophyte (thin black arrow), fatty deposition at the superior aspect of anterior and posterior margins of L4 vertebral body indicating shiny corner sign (thick black arrow), and fatty deposition around L4-5 facet joint (white arrow). (E) Sagittal T1W MR image of lumbosacral spine shows ankylosis of the facet joint (black arrow). Detection of any of these findings in the imaging field in patients with sacroiliitis can support a diagnosis of seronegative spondyloarthropathy

Mentions: Additional findings, when seen in the surrounding structures in the imaging field, can add substantial value to the diagnosis of spondyloarthropathy. Additional CT and MRI findings [Figures 11 and 12] in routine SI joint protocol include the following:
