Sacroiliitis is an inflammation of one or both sacroiliac joints which often causes inflammatory back pain of varying intensity, though some patients may be asymptomatic. Sacroiliitis is a common finding in spondyloarthropathies, being frequently the first manifestation of axial spondyloarthropathie[...]

Role of imaging in the evaluation of sacroiliitis Some important clinical indications for imaging of sacroiliac joints are: to clarify the diagnosis in a patient with inflammatory back pain; to make a diagnosis of ankylosing spondylitis; to determine the amount of inflammation; to determine the am[...]
CT and MRI have an important role in the evaluation of the sacroiliac joints. The radiologist should be familiarized with the CT and MRI characteristics of spondyloarthropathy-related sacroiliitis in order to correctly interpret the imaging findings and avoid misdiagnosis.
