. When fluid builds up in the lungs—usually because the heart cannot pump efficiently (congestive heart failure)—that fluid leaks into the connective tissues of the lung, making them visible on an X-ray. Common Causes While often associated with heart failure, Kerley B lines are not exclusively a heart problem. They can appear in several scenarios: Congestive Heart Failure (CHF): Often due to left-sided heart failure raising pulmonary venous pressure. Mitral Valve Disease: Leading to pulmonary congestion. Lymphangitic Carcinomatosis: Spread of cancer through the lymphatic system. Interstitial Pulmonary Fibrosis: Scarring of the lung tissue. Pneumonia: Specific types like viral or mycoplasma pneumonia. Kerley B Lines vs. A and C Lines Kerley lines come in three main varieties, often seen in cases of severe heart failure, but B lines are the most frequently observed. Kerley A Lines: Longer (2–6 cm), unbranching oblique lines radiating from the center of the lung (hila). Kerley B Lines: Short, horizontal lines at the periphery (base). Kerley C Lines: Short, fine, reticular lines that create a spider-web pattern (less common). Key Takeaway If you or a loved one have a chest X-ray noting the presence of Kerley B lines, it is crucial to discuss this with a healthcare provider. While not always indicating a severe crisis, they are generally a marker of pulmonary edema and require prompt management.
