Kerley C Lines

Kerley C lines occur when the lymphatic vessels within the lung tissue become engorged or when the connective tissue itself becomes scarred or fluid-filled. Because these lines are actually Kerley B lines seen "end-on" or in a random distribution across the lung's surface, they lack the neat, horizontal orientation of B lines. Primary Causes of Kerley C Lines

In acute dyspnea, Kerley C lines + cardiomegaly + pleural effusion = highly likely congestive heart failure . kerley c lines
