Aug 26, 2024 · Septal lines, or Kerley lines, are seen when the interlobular septa in the pulmonary interstitium become prominent. It may be because of lymphatic engorgement or edema of the connective tissues of the interlobular septa. They usually occur when pulmonary capillary wedge pressure reaches 20-25 mmHg.

Feb 4, 2025 · Kerley B lines are an essential radiographic finding that can offer valuable insights into a patient’s pulmonary health. Seen as thin, horizontal lines on chest X-rays, these structures are typically found near the lung bases and are associated with interstitial edema.

Kerley B lines, or septal lines are a sign of interstitial oedema. They represent thickening of the interlobular septa of the periphery of the lungs. If you see Kerley B lines on a chest X-ray in suspected heart failure, then they are a very helpful sign to help diagnose interstitial oedema.

Oct 2, 2024 · Learn to interpret Kerley B lines, a crucial chest X-ray finding, with expert guidance on radiographic patterns, interstitial lung disease, and pulmonary edema diagnosis, enhancing your medical imaging skills. ... Kerley B lines are a crucial diagnostic tool in radiology, particularly in the assessment of patients with respiratory symptoms. ...

Oct 7, 2021 · Kerley B lines are small, horizontal, peripheral straight lines demonstrated at the lung bases that represent thickened interlobular septa on CXR. They represent edema of the interlobular septa and though not specific, they frequently imply left ventricular failure.

Kerley B lines (thickened interlobular septa) are much spoken about as a medical student, but less commonly observed than one might expect given the volume of cardiac failure patients. These thin lines of 1-2 cm are virtually always at the lungs bases and at the lung periphery lying perpendicular to the pleural surface to which they contact.

Feb 5, 2025 · The identification of Kerley B lines on a chest X-ray has significant clinical implications. These lines can indicate the presence of an underlying condition that may require immediate medical attention. For example, in cases of heart failure, the presence of Kerley B lines can suggest increased pulmonary venous pressure, which may necessitate ...

Aug 11, 2018 · Chest x-ray lines and stripes are important to recognize on chest radiographs. Lines are usually less than 1 mm in width and are comprised of tissue outlined on either side by air and typically represent pleural-covered structures within the middle and superior mediastinum 1,2: anterior junction line; posterior junction line

Feb 1, 2014 · On a chest x-ray lung abnormalities will either present as areas of increased density or as areas of decreased density. Lung abnormalities with an increased density - also called opacities - are the most common. In this article we will focus on this four-pattern approach.

Causes of Kerley B lines include pulmonary edema, lymphangitis carcinomatosa and malignant lymphoma, viral and mycoplasmal pneumonia, interstitial pulmonary fibrosis, pneumoconiosis, and sarcoidosis. They can be an evanescent sign on the chest x …
