We report a 59 years old male withsevere sequelae of a previous cerebrovascular accident that consulted in the emergency roomfor fever of 15 days of evolution. A right empyema was diagnosed. The bacteriological cultureof the effusion disclosed the presence of Streptococcus constellatus and two anaerobic strains(Prevotella intermedia and Fusobacterium urealyticus). The patient was treated with apleural drainage and received ceftriaxone and clindamycin during six weeks. He wasdischarged in good conditions and is asymptomatic after eight months of follow up (Rev MedChile 2006; 134: 1030-2).(
