COMMENTS

Patients with congestive heart failure commonly will have increased density of the interstitial markings of the lung fields. Very specific patterns have been described as Kerley "B" or "A" lines. The "B" lines are most commonly cited and when identified imply the presence of interstitial edema in the pulmonary septa. The Kerley "B" lines are short, horizontal lines perpendicular to the lateral aspects of the lung.
