Hi and welcomet to HCM.
It means that there is an inflammatory proces which is usally caused by infection(in this case probably bacterial). SOme other disease can cause lung inflammation such as bronchitis
, autoimmune disorderd but you should rule out pneumonia
first. if you have any symptoms such as cough, fever and fatigue
you should take certain medicines for it.ask your gp about it. This finding isnt serious and it will probably regress in week or 2. WIsh you good health.
