Passive hyperaemia of the of the lungs caused by mitral stenosis or heart failure gives remarkable and very varied x-ray appearances. A severe attack of hyperaemia always leaves permanent radiologic evidence behind it…the shadows of perivascular lymphatics persist as fine, sharp lines, most marked at the bases and near the hila. They are of three types. A Lines several inches long, rather ragged and radiating from the hilum. They do not bifurcate and they do not follow the normal branching pattern of bronchi and vessels. B Short, sharp lines seen only at the bases, usually less than an inch long and running transversely out to touch the pleural margin. C Fine interlacing lines giving the network appearance. It is the fine interlacing lines which have given rise to the term reticulation. Each presents a different [radiologic] pattern due to different arrangement of the connective tissue septa in various parts of the lung. Emergency physician, Sir Charles Gairdner Hospital.

Description Kerley lines are described as types A, B or C. Kerley A lines are linear opacities extending from the periphery to the hila caused by distention of anastomotic channels between peripheral and central lymphatics Kerley B lines are small, horizontal, peripheral straight lines demonstrated at the lung bases that represent thickened interlobular septa on CXR.

Kerley lines are a sign seen on chest radiographs with interstitial pulmonary edema. They are thin linear pulmonary opacities caused by fluid or cellular infiltration into the interstitium of the lungs. They are named after Irish neurologist and radiologist Peter Kerley. They are suggestive for the diagnosis of congestive heart failure , but are also seen in various non-cardiac conditions such as pulmonary fibrosis , interstitial deposition of heavy metal particles or carcinomatosis of the lung. Chronic Kerley B lines may be caused by fibrosis or hemosiderin deposition caused by recurrent pulmonary edema. These are longer at least 2cm and up to 6cm unbranching lines coursing diagonally from the hila out to the periphery of the lungs.

Fine interstitial lines at both bases, greater on the right consistent with interlobular septal thickening. Kerley B lines thickened interlobular septa are much spoken about as a medical student, but less commonly observed than one might expect given the volume of cardiac failure patients. These thin lines of cm are virtually always at the lungs bases and at the lung periphery lying perpendicular to the pleural surface to which they contact. Updating… Please wait.
