Chest X-ray on admission showed symmetrical lung fields with multiple alveolar opacities of nodular appearance with a tendency to coalescence on both lung bases.

Chest X-ray and admission laboratories are shown in Fig. 1 and Table 1, respectively.
Progression of chest computed tomography. Panel A: Computed tomography on admission showed multiple patchy and coalescent areas corresponding to centrilobular micronodules in a tree-in-bud pattern, and discrete areas of ground glass opacities with compromise of both lung fields, especially in the inferior lobes. Panel B: Computed tomography five days from admission showed a significant decrease in multinodular opacities in comparison to the previous study, with persistence of centrilobular micronodules in a tree-in-bud pattern in the superior lobes and lingula. Residual anterior pneumothorax in the right hemithorax and extensive pneumomediastinum and subcutaneous emphysema. Panel C: Computed tomography thirteen days from admission showed complete resolution of ground glass opacities and centrilobular micronodules in comparison to previous studies, resolution of right pneumothorax, and significant decrease of pneumomediastinum and subcutaneous emphysema.

He was taken to the intensive care unit (ICU), and a high-resolution chest tomography was obtained, which is shown in Fig. 2A, revealing multilobar consolidation with centrilobular micronodules configuring a tree-in-bud pattern. A control computed tomography of the chest was performed to check on the pneumomediastinum (Fig. 2B), which revealed a marked improvement in the parenchymal lesions only five days apart from the initial tomography. A complete resolution of tomographic lesions was achieved in less than two weeks after admission, with an almost complete resolution of the pneumomediastinum and subcutaneous emphysema (Fig. 2C).
