Kerley B Lines
Kerley B lines are short lines seen on chest imaging that can suggest fluid-related changes in the lungs, often from heart failure.
When to get help quickly: Urgency depends on the cause. If the person is short of breath, has chest symptoms, or looks acutely unwell, the underlying fluid problem may need urgent review.
Common symptoms
Kerley B lines are an imaging sign rather than a disease, so symptoms usually come from the underlying fluid or heart problem and may include breathlessness, cough, or swelling.
When imaging helps
A chest X-ray helps show this pattern and can support the wider picture of pulmonary edema or congestion when symptoms suggest fluid overload.
What radiology does
Chest X-ray helps identify this pattern and other signs of pulmonary edema or congestion.
What usually happens next
Treatment depends on the underlying cause, often involving heart failure management or other fluid-related care.
