Chest CT scan images at the time of hospital admission (A and B) and before discharge (C and D). Baseline CT images (A-B) show bilateral ground glass opacities with a peripheral and posterior distribution, mainly in the lower lobes, in association with thickened interlobular lines. Small pulmonary nodules are also present in the right lower lobe, many of them distributed in the secondary lobules. Ground glass opacifications localized in lower lobes evolve into parenchymal bands and perilobular consolidations at follow-up CT images (C-D), suggesting the possible presence of organizing pneumonia.
