Pyogenic sacroiliitis in children: Diagnostic dilemma and management.

Pyogenic sacroiliitis is a relatively rare condition in children. Vigilance and careful clinical examination of the joint could minimize the delay in diagnosis. In areas endemic for brucellosis, negative serology, raised erythrocyte sedimentation rate, positive magnetic resonance imaging, isotope bone scan and bacteriological culture confirm diagnosis. Appropriate adequate antibiotic therapy for four to six weeks cures the infection and prevents morbidity.
