Streptococcus anginosus is a gram-positive catalase-negative cocci and commensal flora of the oropharynx and gastrointestinal tract. Streptococcus anginosus is known to be highly virulent and known to cause invasive pyogenic infection which may necessitate emergent surgical treatment. We present a case of a 53-year-old female with dental caries and uncontrolled diabetes mellitus who presented with progressive shortness of breath for 1 week. A computed tomography scan of the chest showed a loculated empyema which was treated with emergent video-assisted thoracoscopic surgery. Pleural fluid culture as well as sputum cultures grew Streptococcus anginosus. The patient was treated intravenous cephalosporins and discharged on oral antibiotics after 14 days with outpatient dental follow-up and improvement of symptoms.
