There is peribronchial thickening in the right perihilar region, which may represent reactive airway disease or early infection. Slightly prominent reticular markings at the right base are noted, potentially due to patient rotation, along with atelectasis along the right lateral hemidiaphragm. The left lung is clear, and no pleural effusion is present.
