what is thickening of the plura mean
Pleural thickening definition. Pleural thickening is a lung disease that describes a scarring, calcification, and/or thickening of the pleura (the lining surrounding the lungs) often as a consequence of the inhalation of asbestos into the lungs.f the asbestos fibres work their way into the pleura, they can cause the pleural thickening condition. Pleural thickening tends to cause sufferers a tightness of the chest or breathlessness which is attributed to the reduced lung function that the thickening causes.
