Magnetic resonance imaging of the sacroiliac joints (SIJ) is now frequently performed to detect subchondral inflammatory and structural changes in patients with early axial spondyloarthritis (SpA). However, similar changes can also occur in various other conditions, which may lead to the overdiagnosis of axial SpA. The aim of this article is to review the key imaging features of the most common disorders that may mimic inflammatory sacroiliitis, including mechanical changes and osteoarthritis, osteitis condensans ilii and pregnancy-related changes, other strain related changes, anatomical variants, pediatric SIJs, hyperostosis, infectious sacroiliitis, SAPHO syndrome, hyperparathyroidism, and sacral stress fractures.
期刊介绍：
Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration.
This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
