Pneumatoceles

Figure 1. Pneumatocele Formation in PCP

Frontal chest radiograph shows bilateral ground glass opacity, with a cystic lesion developing within the ground-glass opacity in the left mid-lung.

 

Figure 2. Extensive Pneumatocele Formation with PCP

Frontal chest radiograph shows bilateral reticulation with preserved lung volumes. If one looks closely, the reticulation can be seen to represent the walls of numerous bilateral cysts (same patient as Figure 12B).

Figure 3. Extensive Pneumatocele Formation with PCP: Resolution.

Frontal chest radiograph of patient in Figure 6 taken 2 years later shows resolution of cysts, with linear left upper lobe scarring.

Figure 4. Spontaneous Pneumothorax in PCP

Frontal chest radiograph shows diffuse bilateral air space opacity with a right-sided pneumothorax.
