CXR in pulmonary alveolar proteinosis (PAP) shows bilateral perihilar infiltrates with consolidation in a "bat-wing" configuration, which may mimic pulmonary edema, although with a typical absence of cardiomegaly or pleural effusion. Unilateral involvement occurs occasionally, and lymphadenopathy is rarely present. Typically, changes progress over weeks to months into a diffuse reticulogranular pattern.
