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.

Figure 15: Degenerative arthrosis in sacroiliac joints. Oblique coronal CT scan shows osteophytes (thick black arrows), subchondral cyst (thin black arrow), vaccum phenomenon (short white arrow), and subchondral sclerosis (long white arrow)

Mentions: Degenerative changes [Figure 15]: It is associated with marginal osteophytes, periarticular joint space narrowing, and subchondral cysts in the absence of erosion. The area of involvement is typically anterior and middle half of the SI joint compared to involvement of posterior third in spondyloarthropathy-related sacroiliitis[2]
