Preferred Label : Kerley B lines;
Definition : These are short parallel lines at the lung periphery. These lines represent interlobular
septa, which are usually less than 1 cm in length and parallel to one another at right
angles to the pleura. They are located peripherally in contact with the pleura, but
are generally absent along fissural surfaces. They may be seen in any zone but are
most frequently observed at the lung bases at the costophrenic angles on the PA radiograph,
and in the substernal region on lateral radiographs. Kerley B lines are seen in Congestive
Heart Failure (CHF) and Interstitial Lung Diseases (ILD).;
