title: Isolated polyarticular septic arthritis: an atypical presentation of meningococcal infection.
abstract: We are presenting a case of a 19-year-old college student with sudden-onset, asymmetric polyarticular arthritis with Neisseria meningitidis 10 days after an acute upper respiratory infection consisting of fevers, chills, pharyngitis, and productive cough. Primary meningococcal septic arthritis is a rare entity. A majority of these cases present in a monoarticular fashion. The synovial fluid findings, although compatible with inflammatory arthritis, are not typical of septic arthritis. This entity, although rare, should be considered in the differential diagnosis of septic arthritis of large joints, especially since N. meningitiditis does not grow well on routine culture media. A literature review on the diagnosis, treatment, and prevention of primary meningococcal septic arthritis is presented.
