Occupational dust exposure causing chronic inflammation. Lines remain permanent and do not resolve with diuretics. 5. Acute Respiratory Distress Syndrome (ARDS) Non-cardiogenic pulmonary edema. Increased capillary permeability causes fluid leakage. Radiographic Identification

The lung anatomy contains connective tissue sheets called interlobular septa. These septa separate pulmonary lobules. They contain lymph capillaries and small veins. Occupational dust exposure causing chronic inflammation
The presence of these lines signifies that the interstitial space between lung lobules is filled with fluid or cellular material. These septa separate pulmonary lobules

Kerley B lines are short, thin, horizontal lines visible on a chest X-ray that indicate the thickening of interlobular septa, most commonly due to pulmonary edema . Key Characteristics
