📍 They represent thickened interlobular septa due to fluid, cells, or fibrosis. In acute settings, think: pulmonary edema (fluid in the septa).

👩‍⚕️ Next time you see tiny horizontal lines at the lung bases, don’t dismiss them as artifact—think about the heart.

📍 On a supine portable chest X-ray, Kerley B lines may be subtle or absent. Look for peribronchial cuffing and cephalization as additional signs of elevated pulmonary venous pressure.
