What does it mean if right pleural thickening shows up in medical tests, like during GCC medicals? I had an x-ray done on my own, and the radiologist didn't see an issue, but another one mentioned I could go for more scans although they didn't expect anything serious to turn up. What could be causing this, and is it something that can be fully treated?

Pleural thickening is common and is due previos infection.if you have no symptoms you can completely ignore it will self heal
