Figure 5 (A) PA chest radiograph from a patient with pulmonary alveolar proteinosis (PAP) shows extensive alveolar opacification involving all lung fields. The patient was severely hypoxemic. (B) PA chest radiograph from the same patient 4 weeks following bilateral whole lung lavage shows marked, albeit partial, clearing.
