Chest CT images performed on three different moments of clinical evolution. A: Outpatient study, showing bilateral, rounded foci of consolidation and ground-glass images, in <50% of the lung fields. B: At admission, showing bilateral consolidations and ground-glass images, occupying >50% of the lung fields. C: On the worst day after admission, with an increase of the ground-glass opacities, which became confluent and associated with interlobular septal thickening and bilateral consolidation. Arrows point out some of the pulmonary lesions of the patient.
