5. The chest radiograph shows upper lobe peripheral consolidation and reticulation
The frontal chest radiograph shows upper lobe, peripherally predominant opacities consisting of consolidation, best seen in the subpleural left upper lobe, and underlying linear and reticular opacities. These findings are not basal predominant. No nodules are present. Some areas of airway thickening are difficult to exclude but clear evidence of bronchiectasis is lacking. The lung volumes are normal to increased, although the diaphragms are not flattened, but no cystic change is present.
Which of the following is an appropriate consideration among the differential diagnostic possibilities for the appearance of the patient’s chest radiograph?
