What are pulmonary infiltrates?
An infiltrate is the filling of airspaces with fluid (pulmonary oedema), inflammatory exudates (white cells or pus, protein and immunological substances), or cells (malignant cells, red cells or haemorrhage) that fill a region of lung and increase the visual impression of increased soft tissue density.
Pulmonary infiltrates are associated with pneumonia, tuberculosis, and nocardiosis.
Pulmonary infiltrates can be observed on a chest radiograph.
