While classically associated with fluid overload, they can occur in various conditions:
In a healthy state, these septa are invisible on a conventional chest radiograph. However, when the pulmonary capillary wedge pressure (PCWP) climbs to 20–25 mmHg , fluid spills out into the interstitium. kerley b lines cxr
Comprehensive Guide to Kerley B Lines on Chest X-Ray (CXR) are a crucial diagnostic finding on a chest radiograph , serving as a classic indicator of interstitial pulmonary edema . First described by Irish radiologist Sir Peter Kerley in 1933, these lines reveal underlying fluid accumulation, cellular infiltration, or fibrotic changes within the lung tissue. Recognizing Kerley B lines on a chest X-ray (CXR) allows clinicians to quickly identify severe conditions like congestive heart failure (CHF) and direct targeted medical intervention. Anatomy and Pathophysiology While classically associated with fluid overload, they can
Kerley B lines are small, thin, linear opacities seen most commonly in the lung peripheries. On a standard frontal chest radiograph, they are characterized by: First described by Irish radiologist Sir Peter Kerley
