Adenopathy More Condition_symptoms What Does Hilat Bilar Adenopathy Mean?

What does hilat bilar adenopathy mean? - adenopathy more condition_symptoms

Please can someone guide me? My husband was sent for a CAT scan b / c our doc was concerned about the lung is not working properly (I said he could barely hear)
Nobody tells us anything or what happened.
And this is normal, if only one lung is slightly shorter than the other? I saw that his right lung is shorter during the test.
Thanks in advance!
