Kerley lines are named after Peter J. Kerley, a British radiologist, who identified types of septal lines on chest radiographs in patients with congestive heart failure.
|Kerley A lines||linear opacities usually 2 - 6 cm long radiating from the hila into the periphery, caused by distention of lymphatic channels between perivenous and peribronchovascular lymphatics|
|Kerley B lines||short (<2cm) thin horizontal lines extending perpendicularly from the lateral pleural surface in the lung bases, caused by thickening of interlobular septa|
|Kerley C lines||reticular opacities in the lung bases that represent Kerley B lines en face.|
