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.

Hyperparathyroidism. Oblique coronal CT scan images through sacroiliac joint in a 40 year old female (A, B) show diffuse osteopenia (black arrows) with subchondral erosions (white arrows). Bilateral hand radiographs (C) in the same patient demonstrate generalized osteopenia with subperiosteal bone resorption (white arrows) particularly involving the radial aspects of the second and third middle phalanges

Figure 18: Hyperparathyroidism. Oblique coronal CT scan images through sacroiliac joint in a 40 year old female (A, B) show diffuse osteopenia (black arrows) with subchondral erosions (white arrows). Bilateral hand radiographs (C) in the same patient demonstrate generalized osteopenia with subperiosteal bone resorption (white arrows) particularly involving the radial aspects of the second and third middle phalanges

Mentions: Hyperparathyroidism [Figure 18]: Hyperparathyroidism can present with bilateral symmetric or asymmetric SI joint widening with subchondral erosions. Presence of abnormal bone density, subperiosteal, subligamentous erosions, and involvement of other bones helps in differentiation.
