Pediatric Sacroiliitis

Abstract

PSI in infants and adolescents may represent 2 different conditions. Although PSI is mainly caused by S. aureus in the children-adolescent group, clinical manifestations and biologic characteristics of PSI in infants suggest Kingella kingae as the etiology osteoarticular infection. Thus, oropharyngeal swab polymerase chain reaction assay for K. kingae and magnetic resonance imaging should be considered for early diagnosis and treatment of this condition in the younger age group.
