What is Pleural Plaques?
Pleural Plaques are areas of thickening which occur on the parietal pleura, most commonly on the lower chest walls and diaphragm. These changes are visible on x-ray. In most cases a person will not be aware of pleural plaques, as they are commonly symptomless. Plaques are simply a marker of asbestos exposure and usually do not develop until 20 years or more after first exposure to asbestos.
