: They are specifically found in the retrosternal clear space (the lucent area directly behind the sternum) on a lateral X-ray.

. PubMed Central (PMC) (.gov) +2 Comparison of Kerley Lines In clinical practice, Kerley lines (named after radiologist Peter Kerley ) are categorized by their location and orientation: Type Appearance Location on X-ray Primary Cause Kerley A Long (2–6 cm), diagonal Mid-to-upper lung zones, radiating from hilum Lymphatic distension or fibrosis Kerley B Short (1–2 cm), horizontal Lung bases, perpendicular to the pleura Interstitial edema (classic CHF sign) Kerley C Fine, criss-cross Throughout lung fields (reticular pattern) Overlapping A/B lines or diffuse infiltration Kerley D Identical to Kerley B Retrosternal clear space (Lateral view) Pulmonary fibrosis or interstitial edema Clinical Importance Finding Kerley D lines on a lateral X-ray is often an early indicator of kerley d lines

Kerley B lines are short, horizontal lines at the lung periphery, typically seen at the costophrenic angles on a chest X-ray. They are a type of interstitial lung marking that represents interstitial edema or fibrosis. These lines are usually 1-2 mm in length and are perpendicular to the pleural surface. : They are specifically found in the retrosternal

To successfully identify Kerley D lines, a radiologist must closely inspect the . They are a type of interstitial lung marking

The eponymous classification stems from the pioneering work of Irish neurologist and radiologist Sir Peter James Kerley, who characterized specific linear patterns on chest radiographs caused by interstitial alterations.
