The correct answer is C
Pulmonary pneumatoceles are thin-walled, air-filled cysts that develop within the lung parenchyma. They can be single emphysematous lesions but more often are multiple, thin-walled, air-filled, cystlike cavities. Most often, they occur as a sequela to acute pneumonia, commonly caused by Staphylococcus aureus. Incidence of postinfectious pneumatocele formation ranges from 2-8% of all cases of pneumonia in children. However, the frequency can be as high as 85% in staphylococcal pneumonias.
