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.
