Symptoms of Pleural Thickening
Most cases of pleural thickening are asymptomatic. Pleural thickening is relatively common and refers to an increase in pleural thickness resulting from fibrosis—caused by fibrin deposition and granulation tissue proliferation—on the basis of pleural disease. It often occurs as a sequela following resolution of exudative pleuritis or pleural effusion.
Pleural thickening may be localized or diffuse. Diffuse visceral pleural thickening can impair pulmonary respiratory function, whereas diffuse parietal pleural thickening may narrow the intercostal spaces and reduce thoracic volume.
Most cases of pleural thickening require no specific treatment. Mild chest tightness, if present, typically diminishes or resolves gradually through physiological compensation. Regular physical exercise—particularly chest-expanding and deep-breathing exercises—can yield favorable therapeutic effects.
