A. Baseline CXR in a ten-year-old boy with fever, cough, and dyspnoea. There were multifocal GGOs in both lungs and a consolidation in left inferior lobe. The consolidation is depicted as an increased retrocardiac density and loss of the silhouette of the diaphragm. B. Diffuse bilateral coalescent consolidations appeared 24 h after. No pleural effusion was seen on ultrasound. Findings were consistent with acute respiratory distress syndrome. C. In the follow up CXR 24 h later, bilateral progression was seen. D. 8 days after the initial radiograph most of the lung injury had already resolved.
