This study presents two cases of septic arthritis occurring during invasive bacterial meningitis, primarily due to hematogenous dissemination during bacteremia. The cases involved a 17-year-old student with H. influenzae infection and a 14-year-old student with co-infection by Neisseria meningitidis and Streptococcus pyogenes. Both patients exhibited severe symptoms, including intense headaches, fever, and purpura fulminans-like syndrome. The diagnosis was confirmed through lumbar puncture and molecular biology techniques, revealing gram-negative bacilli and H. influenzae in the cerebrospinal fluid. Treatment included antibiotic therapy and supportive care, with both patients recovering after hospitalization. The study highlights the importance of early diagnosis and appropriate antibiotic therapy in managing meningococcal arthritis, emphasizing the need for cautious interpretation of molecular results in the clinical context.
