Lung Infiltrates (Medical Definition) | Quick Explainer Video

Lung infiltrates refer to the abnormal accumulation of substances such as fluid, cells, or bacteria in the lung tissue. This condition can be seen on a chest X-ray or CT scan and is often a sign of an underlying infection, inflammation, or injury to the lungs. Common causes of lung infiltrates include pneumonia, pulmonary edema, and acute respiratory distress syndrome. Treatment for lung infiltrates depends on the underlying cause and may include antibiotics, steroids, or supportive care to help improve lung function and resolve the infiltrates.
