A 77-year-old woman with fever, cough and sore throat for five days. (a) Initial chest radiograph on admission is normal. (b) Follow-up radiograph performed two days later shows interval development of multifocal ground-glass opacities in the bilateral lower zones (arrowheads). The patient deteriorated during admission and required intensive care admission for mechanical ventilation. (c) Radiograph obtained on Day 11 of admission shows progression of lung changes with multifocal bilateral lung consolidation, worse in the left lung.
