A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. Pulmonary infiltrates are associated with pneumonia, tuberculosis, and nocardiosis. Pulmonary infiltrates can be observed on a chest radiograph.
Any abnormal density will show up in the otherwise air filled lungs. Usually the infiltrate will mean pneumonia, or some sort of infection with edema/swelling that is in the lung. You could also have a cancer for instance that would cause pleural/lung fluid build up that would be considered an infiltrate.
