Pyogene sakroiliitis

Background. Pyogenic sacroiliitis is a rare infectious disease of the sacroiliac joint. Despite typical symptoms, the diagnosis is often delayed and thus, early and efficient therapy is delayed as well. Case report. We report a bout a 15 year old female patient with pyogenic sacroiliitis without prior trauma or injury. The patient displayed sudden acute febrile onset of joints and buttock pain. Four weeks later she presented in our clinic with severe pain in the right gluteal region and elevated ESR and CRP. The diagnosis was confirmed by scintigraphy and magnetic resonance imaging. Computed tomography guided needle biopsy revealed staphylococcus aureus as causative microorganism. After antibiotic treatment for 11 weeks the patient was free of any symptoms and laboratory activity parameters were normal. Discussion. In pyogenic arthritis full recovery can be achieved upon prompt and appropriate treatment. The knowledge of the typical symptoms enables early diagnosis and treatment.
