Kerley lines are thin, linear opacities seen on chest X-rays that indicate . They represent thickening of the interlobular septa due to fluid, cellular infiltration, or fibrosis. In clinical practice, they are most often a classic sign of congestive heart failure. Summary of Kerley Line Types Description Clinical Significance Kerley A
Longer (2–6 cm) lines radiating from the hilum toward the periphery. Upper and mid-lung zones.
To understand Kerley lines, you must understand lung anatomy.
Represent distended lymphatic channels; rarely seen without B lines.
Short (1–2 cm), horizontal lines perpendicular to the pleural surface. Lung bases (costophrenic angles).
Kerley lines are linear opacities seen on chest radiographs, representing a key radiographic sign of . First described by British radiologist Peter Kerley in the 1950s, these lines reflect fluid accumulation within the pulmonary interstitium—the supportive tissue framework of the lungs.
