Abstract

Alveolar proteinosis is a rare pulmonary disease characterized by intra-alveolar accumulation of surfactant composed of lipoproteinaceous material, related to a lack of surfactant resorption by alveolar macrophages. Crazy paving pattern is characteristic, but not specific. The multinodular forms of this affection remain exceptional.
