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.

Osteitis condensans ilii. (A) Oblique coronal CT scan through sacroiliac joint in a 31 year old female shows triangular area of subchondral sclerosis on iliac sides (white arrows) with smooth articular surfaces. (B) Corresponding oblique coronal T1W image without fat suppression shows triangular area of subchondral sclerosis with normal articular surfaces (white arrow)

Figure 14: Osteitis condensans ilii. (A) Oblique coronal CT scan through sacroiliac joint in a 31 year old female shows triangular area of subchondral sclerosis on iliac sides (white arrows) with smooth articular surfaces. (B) Corresponding oblique coronal T1W image without fat suppression shows triangular area of subchondral sclerosis with normal articular surfaces (white arrow)

Mentions: Osteitis condensans ilii [Figure 14]: It can resemble subchondral sclerosis seen in chronic stages of sacroiliitis on both CT and MRI. It is commonly seen in multiparous woman. Sclerosis is seen to involve the bilateral iliac surfaces in the absence of bone marrow oedema, erosions, and joint space narrowing
