case_images: Figure 1 presents a timeline of the hospitalization, including test, examinations, and treatments.
case_images: Depicts a chest x-ray obtained 2 days post-admission to the hospital, illustrating bilateral diffuse patchy infiltrates and consolidations in the upper and lower lobes of the right lung. The chest x-ray was conducted with the patient in a supine position.

case_images: (a) 4 days post-admission: a chest high-resolution computed tomography (HRCT) scan revealed central lobular nodules distributed across all lung lobes, suggesting an origin of the disease from the airways/bronchioles. Primary peribronchial consolidative infiltrates were identified in both lung fields, with the most prominent consolidation observed in the right upper lobe, along with consolidations in both lower lobes featuring air bronchograms. The overall findings primarily evoked suspicion of a pneumonic etiology. (b) 3 1/2 weeks post-admission: this chest HRCT demonstrated visible regression in comparison to the previous imaging studies. However, diffuse, and widespread small centrilobular nodules persisted, along with a notable sublobar atelectasis. No new infiltrates, pleural, or pericardial effusions were evident. The patient remained intubated, with the endotracheal tube tip positioned approximately 3,5 cm from the carina.

case_images: However, the chest HRCT revealed bilateral consolidations, notable consolidation in the lower lobes bilaterally, featuring visible air bronchograms, bilateral peribronchovascular infiltrates, and bilateral patchy infiltrates displaying diffuse ground glass opacities, as seen in Figure 3.
