Abstract：
Hyperostosis triangularis ilii, also called osteitis condensans ilii (OCI), is a rare condition, mostly occurring in females, and the etiology is unknown. This disease is a sclerotic disorder associated with iliac fibrosis, a noninflammatory and self-limiting disorder. This condition primarily affects the iliac part of the sacroiliac joints and sometimes the adjoining bones, such as the sacrum, lumbar vertebrae, and iliac bones. It is an incidental finding in many individuals but rarely associated with lower back pain due to sacroiliac joint involvement. It is mainly treated with physical therapy and medications. OCI should be considered a cause of chronic back pain in females not having ankylosing spondylitis or inflammatory arthritis. Herein, a case of osteitis condensans ilii in a 47-year-old female, presenting with the chief complaints of intermittent lower back pain in the midline and on both sacroiliac regions, without any evidence of ankylosing spondylosis and the X-ray of the pelvis and magnetic resonance imaging (MRI) showing features of OCI, is being reported. The case was managed with medications and exercise, and the patient is under regular follow-up.
摘要：
三角骨增生，也称为凝聚性骨炎(OCI)，是一种罕见的情况，主要发生在女性身上，病因不明.这种疾病是一种与髂骨纤维化相关的硬化性疾病，一种非炎症性和自限性疾病。这种情况主要影响骶髂关节的髂关节部分，有时影响毗邻的骨骼，比如骶骨，腰椎,和髂骨.这是许多人的偶然发现，但由于骶髂关节受累而很少与下背痛相关。它主要是用物理治疗和药物治疗。OCI应被认为是没有强直性脊柱炎或炎性关节炎的女性慢性背痛的原因。在这里，一名47岁的女性患有骨炎，在中线和两个骶髂区域出现间歇性下背痛的主要主诉，据报道，没有任何强直性脊柱病的证据，骨盆的X射线和磁共振成像（MRI）显示OCI的特征。该病例通过药物和运动进行管理，患者正在接受定期随访。
