Q:
What are pulmonary infiltrates?
A:
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.
