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.
目前，骶髂关节（SIJ）的磁共振成像常用于检测早期轴性脊柱关节炎（SpA）患者的软骨下炎症和结构变化。然而，类似的变化也可能出现在其他各种病症中，这可能导致轴性SpA的过度诊断。本文旨在综述可能模拟炎性骶髂关节炎的最常见病症的关键影像学特征，包括机械性改变和骨关节炎、致密性骨炎和妊娠相关改变、其他劳损相关改变、解剖变异、儿童骶髂关节、骨质增生、感染性骶髂关节炎、滑膜炎、痤疮、脓疱病、骨肥厚和骨炎综合征（SAPHO综合征）、甲状旁腺功能亢进以及骶骨应力性骨折。
