A 14-year-old child presenting with 5 days of fever, cough, and sore throat. Over the next 24 h the patient developed progressive respiratory and multi-organ failure. S. constellatus (of the S. anginosus group) was cultured from pleural fluid collected on the second day of hospitalization. a Initial plain chest radiograph showing a dense right upper zone airspace opacity and lingula airspace changes, consistent with multi-focal pneumonia. The following images were performed 24 h later. b Plain chest radiograph with the child intubated and ventilated revealing cavitation in the right mid to upper zones, pleural effusion and more general airspace changes bilaterally. c Computed tomography (CT) scan, coronal view, demonstrating non-enhancing area (necrotic) thin-walled cavities within the right upper lobe and lingula. d Lung ultrasonographic image displaying thin-walled cavities in the lingula region of the left lung
