What does pleural nodularity mean?

Nodular pleural thickening is a form of pleural thickening. Nearly all common causes of nodular pleural thickening are malignant.

Usually, the disease shows very little symptoms at the beginning. As the conditions progress, patients are very likely to experience chest pain and breathing difficulty.


Generally, pleural thickening is the result of prolonged exposure to asbestos. The microscopic mineral fibers of asbestos dust become embedded in the lungs and cause inflammation response.

For people with the conditions, the symptoms may arise within a year, or may not arise until decades later.

Other causes of pleural thickening may include:

  • Chronic pneumonia
  • Tuberculosis
  • Pleura infection caused by the accumulation of pus and blood
  • Coronary artery bypass grafting surgery
  • Radiation exposure


  • Chest pain
  • Breathing difficulty


Nodular pleural thickening is irreversible. Doctors often use therapies to treat the conditions.

There’s evidence that pulmonary rehabilitation is significantly beneficial to people with the disease. This treatment method includes moderate-intensity exercise training, helping the patients to breathe easier.

In progressive cases, patients also receive pleurectomy surgery. The surgery removes parts of the pleura and other nearby linings of the chest.

If you have any doubts about the treatment, please go to the doctor and ask for more professional advice.
