4. The chest radiograph shows mild streaky central opacities, possibly reflecting airway thickening
The pulmonary vascularity is normal and symmetric bilaterally, and there is no evidence of small nodules in either lung. Lung volumes appear normal. There is some mild central interstitial thickening that may represent airway thickening, manifesting as streaky opacities, best seen in the retrocardiac region on the lateral projection. While some linear opacities are present, these findings are not basal predominant and are not suggestive of fibrotic lung disease. No features to suggest cystic pulmonary abnormalities, including curvilinear opacities (which can reflect visualization of the walls of cysts) are present.
The patient was treated with azithromycin, with some improvement in symptoms, although not complete resolution, and she presented to the emergency room with essentially the same complaints several days later.
