Septic sacroiliitis is often difficult to diagnose because the clinical findings can be misleading and the radiological signs delayed.
A 16-year-old adolescent was hospitalized with a history of fever and painful hip. The initial hypothesis of hip osteoarthritis was not confirmed by ultrasonography or CT-scan. The bone scan was also normal. The definitive diagnosis of sacroiliitis was made 1 week later based on the clinical evolution and a positive blood culture. It was confirmed by a second bone scan and MR imaging.
Examination of the sacroiliac joint needs several different tests. Although the initial bone scan may be normal, an osteoarticular infection cannot be definitively ruled out and iterative radiological investigation is warranted. MR imaging may be an additional diagnostic tool for detecting sacroiliitis.
化脓性骶髂关节炎常难以诊断，因为临床表现可能具有误导性，且放射学征象出现较晚。
一名16岁青少年因发热和髋关节疼痛病史入院。超声检查或CT扫描未证实髋关节骨关节炎的初步假设。骨扫描也正常。1周后根据临床进展和血培养阳性确诊为骶髂关节炎。第二次骨扫描和磁共振成像证实了诊断。
骶髂关节检查需要多种不同的检查。尽管初始骨扫描可能正常，但不能完全排除骨关节感染，需要反复进行放射学检查。磁共振成像可能是检测骶髂关节炎的另一种诊断工具。
