Kerley C Line __hot__ -

First described by the Irish radiologist Peter Kerley in the 1930s, Kerley lines are linear opacities seen on chest radiographs of patients with pulmonary venous hypertension. While Kerley A lines (long, linear opacities radiating from the hila) and Kerley B lines (short, horizontal lines at the lung bases) are well-documented, Kerley C lines are often overlooked or mischaracterized. Understanding all three patterns is crucial for accurate interpretation of interstitial lung fluid.

Abstract Kerley C lines are a lesser-known but important radiographic sign of interstitial pulmonary edema. Unlike the more commonly recognized Kerley A and B lines, C lines are fine, reticular opacities predominantly seen in the lower and mid-zones of the lungs. This paper reviews their historical context, anatomical-pathological correlation, radiographic identification, and clinical relevance, emphasizing their role in the early detection of elevated pulmonary capillary wedge pressure. kerley c line
