Passive hyperaemia of the of the lungs caused by mitral stenosis or heart failure gives remarkable and very varied x-ray appearances, kerley b lines. 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.

At the time the article was last revised Joachim Feger had no financial relationships to ineligible companies to disclose. Septal lines , or Kerley lines , are seen when the interlobular septa in the pulmonary interstitium become prominent. It may be because of lymphatic engorgement or edema of the connective tissues of the interlobular septa. They usually occur when pulmonary capillary wedge pressure reaches mmHg. They represent the thickening of the interlobular septa that contain lymphatic connections between the perivenous and broncho-arterial lymphatics deep within the lung parenchyma. On chest radiographs, they are seen to cross normal vascular markings and extend radially from the hilum to the upper lobes.

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.

Kerley B lines are a radiological sign observed on chest x-rays and can be a valuable diagnostic tool in respiratory care. This article will provide an overview of Kerley B lines, including their appearance, underlying causes, and clinical significance. Kerley B lines are named after an Irish radiologist by the name of Peter Kerley , who first described these findings in These are short, thin, horizontal lines located at the periphery of the lungs, usually towards the lung bases. These lines measure around centimeters in length and are typically less than 1 millimeter in thickness. The orientation of these lines is perpendicular to the nearby pleura, which is the membrane that covers the lungs. On a chest x-ray, Kerley B lines appear as short, thin, horizontal lines located at the periphery of the lungs, usually towards the lung bases.

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.
