Cxr Kerley B Lines -

Kerley B lines are short, horizontal lines at the lung periphery, typically seen at the costophrenic angles. They are a type of interstitial marking that represents interstitial edema or fibrosis. These lines are usually 1-2 mm long and are perpendicular to the pleural surface.

To understand Kerley B lines, one must first understand the anatomy of the lung interstitium. cxr kerley b lines

While Kerley B lines are the most famous, Kerley described three patterns of septal lines: To understand Kerley B lines, one must first

In chronic interstitial lung diseases (e.g., Pulmonary Fibrosis, Connective Tissue Disease), the septa can thicken due to scar tissue rather than fluid. However, fibrosis lines are often irregular and associated with honeycombing or traction bronchiectasis, helping to differentiate them from the smooth lines of edema.

While pulmonary edema is the most frequent cause, Kerley B lines are not exclusive to heart failure. They can result from any condition that causes the interlobular septa to thicken.
