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.

Asymmetrical sacroiliitis. (A) Coronal oblique CT scan in a 51 year old female with psoriasis shows bilateral diffuse reduction in joint spaces, blurring of articular cartilage on the right side (thin black arrow), multiple erosions in the left ilium (white arrow), and subchondral sclerosis on both iliac and sacral sides (thick black arrow). (B) Coronal oblique CT scan in another case shows multiple erosions in the left ilium (black arrow) with subchondral sclerosis (white arrow) and few erosions on the right iliac and sacral surfaces (black arrows)
