Meningitis fulminante por Streptococcus pyogenes

Streptococcus pyogenes, or group A Streptococcus, rarely causes bacterial meningitis in adults but has a high mortality rate if untreated. This bacterium has become more aggressive and shows greater invasive capacity, increasing the incidence and severity of infections. These observations have led to the hypothesis of a more virulent strain.

We report the case of a healthy 54-year-old woman with neck pain and rapid neurological and hemodynamic worsening despite appropriate antibiotic and corticosteroid treatment who died 5 hours after admission.
