Chronic Kerley B lines in congestive heart failure

Case contributed by Dr Balint Botz

Presentation

Known CHF with multiple exacerbations. Worsening dyspnea.

Patient Data

Age: 90 years
Gender: Male
  • Enlarged heart and pulmonary vasculature.
  • Prominent thickening of the interstitial septae
  • Characteristic, unusually thick Kerley B lines best observed in the typical peripheral right basal lung zone (see magnified key image).

Case Discussion

After multiple episodes of pulmonary interstitial edema due to CHF the septal lines of the lung can undergo fibrous transformation, which results in the Kerley B-lines becoming permanent. Afterwards therefore these chronic septal lines are no longer predictive of the clinical severity of the disease.
