A chest x-ray (Figure 1) showed patchy bilateral lower zone and right upper zone air-space changes.
Non-contrast high resolution computed tomography axial image of the thorax with white arrows showing bilateral, circumscribed areas of ground-glass opacification in both lungs with associated reticular changes.

High resolution computed tomography (HRCT) of the thorax (Figure 2) showed bilateral extensive, circumscribed areas of ground-glass opacification throughout both lung fields associated with a fine reticular pattern in keeping with pneumonitis.
Non-contrast high resolution computed tomography axial image of the thorax showing an irregular thick-walled right upper lobe cavitary lesion (arrow) with adjacent multiseptated cavitary lesion (arrowhead). Faint bilateral circumscribed areas of ground glass opacification are seen in both lungs with associated reticulated chages (curved arrows).

However, a repeat HRCT thorax (Figure 3) 4 weeks later showed new cavitary lesions.
Chest X-ray (A) and contrast-enhanced computed tomography (CT) axial image of the thorax (B) showing right-sided pneumothorax with bilateral thick-walled cavities. The subcutaneous emphysema seen on CT is due to the presence of a right-sided chest drain (not shown).

Chest x-ray (Figure 4A) and CT thorax (Figure 4B) showed enlarged thick-walled cavitary lesions in both lungs, with a moderate-sized right pneumothorax.
