Abstract
Few cases of bacteremic pneumonia by Neisseria meningitidis (NM) have been described worldwide; mostly in elderly patients or those with comorbidities. They appear clinically indistinguishable from other acute infectious pneumoniae, that do not develope the syndrome of meningococcemia. We report a 17-years-old male, without prior medical history, consulting in the emergency department with a 7-day history of productive cough, right pleural pain, fever and dyspnea. He was admitted to the ICU due to septic shock and respiratory distress. He was managed with vasoactive drugs and prone positioning ventilation for 48 hours. Chest radiography showed a right superior lobe condensation. The electrocardiogram and echocardiogram suggested septic myocarditis. Blood cultures demonstrated the presence of serogroup W135-NM. A lumbar puncture ruled out meningitis, and a 10-day ceftriaxone therapy was completed favorably.
