- Figure 1.
Chest radiograph of a patient with auto-immune pulmonary alveolar proteinosis showing diffuse alveolar opacities with a peri-hilar and basal distribution.
- Figure 2.
Chest computed tomography scan of a patient with auto-immune pulmonary alveolar proteinosis. Reticulations are superimposed on ground-glass opacities forming a “crazy paving” pattern with a geographic distribution: juxtaposition of healthy and sick zones. a) A horizontal section and b) a coronal section.
- Figure 3.
Bronchoalveolar lavage fluid with a milky appearance in a) normal saline compared to b) pulmonary alveolar proteinosis.
- Figure 4.
Periodic acid-Schiff (PAS) staining of bronchoalveolar lavage fluid with pulmonary alveolar proteinosis showing extracellular globular hyaline material homogeneously PAS positive with large, foamy macrophages containing eosinophilic granules. Magnification 400x.
- Figure 5.
Ultrastructural analysis of bronchoalveolar lavage fluid with pulmonary alveolar proteinosis showing numerous lamellar bodies.
- Figure 6.
Chest computed tomography (CT) scan of a patient with pulmonary alveolar proteinosis secondary to myelodysplastic syndrome. The CT scan shows ground-glass opacities and reticulations mainly in the lower zone with patchy, slightly peripheral distribution. a) A horizontal section and b) coronal section.
