It is listed as mild. If you are not having any symptoms of shortness of breath or significant pleural type pain, it is probably just a finding on whatever study it was taken from (x-ray, CT, MRI). Was the study done for pleural problems or somethings else and this was just an incidental finding?
You don't say how old your are or what you have done in your life. If you are a smoker or have worked somewhere with dust, coal, smoke, or other lung irritants, this is not an uncommon finding.
You should discuss this with your physician. It has to be reviewed in correlation with your history and examination. Good luck.
