Kerley B Lines Indicate -

Kerley B lines represent thickening of the interlobular septa—the fine connective tissue partitions between the secondary pulmonary lobules. Normally invisible on X-ray, these septa become apparent when distended or infiltrated by fluid, cells, or fibrous tissue.

Kerley B lines are not a diagnosis but a visual clue on chest X-ray pointing to interstitial pathology—most commonly interstitial pulmonary edema due to congestive heart failure. Recognizing them allows clinicians to initiate appropriate diuretic and heart failure therapy promptly, potentially preventing progression to alveolar edema and respiratory failure. kerley b lines indicate

When a radiologist reports Kerley B lines in an acute setting, think . They are a reliable and early indicator of elevated left atrial pressure (usually > 15–20 mmHg). Their presence should prompt clinical evaluation for jugular venous distension, crackles on auscultation, S3 gallop, and measurement of brain natriuretic peptide (BNP) or echocardiography.

Kerley B lines are small, thin, horizontal lines most often seen in the peripheral lung fields, particularly near the costophrenic angles. They are a hallmark radiographic finding on a standard chest X-ray. Their presence should prompt clinical evaluation for jugular
