Kerley's B Lines [work]

Kerley’s B lines are small, linear opacities seen most often in the lung peripheries, particularly at the costophrenic angles. They are:

Differential Diagnosis Although strongly suggestive of CHF, Kerley B lines can be caused by other conditions that thicken the pulmonary interstitium: Wikipedia +1 Cardiac: Mitral stenosis, left ventricular failure. Malignancy: Lymphangitic carcinomatosis (often asymmetrical). Infection: Viral, mycoplasmal, or Pneumocystis pneumonia. Chronic Disease: Sarcoidosis, pneumoconiosis, and interstitial pulmonary fibrosis. Other: Volume overload from IV fluids, renal insufficiency. Radiopaedia +8 5. Diagnostic Nuances Ultrasound (POCUS): Note that "B-lines" on lung ultrasound are different; they are kerley's b lines

Kerley's B lines are a radiological finding seen on chest X-rays, which are a crucial diagnostic tool for various pulmonary and cardiac conditions. These lines are a type of interstitial lung marking that can indicate the presence of interstitial edema, fibrosis, or other lung pathologies. In this guide, we will explore the definition, causes, radiological features, clinical significance, and differential diagnosis of Kerley's B lines. Kerley’s B lines are small, linear opacities seen

So next time you see a chest X-ray with fine peripheral lines, stop and think: Is that the lung crying out before the flood? If yes, you’ve just spotted one of radiology’s most satisfying signs—and possibly saved a patient from drowning from the inside out. Radiopaedia Kerley Lines - an overview | ScienceDirect

The presence of Kerley's B lines on a chest X-ray can indicate:

The spread of cancer (such as lung, breast, or stomach) through the lymphatic system can cause persistent septal thickening.
