Hello and thank you for posting your query on HCM
Presence of tiny piri-hilar opacities in lung field can be due to calcified lymph
We are exposed to a large number of infectious agents from our birth. These infections cause non-specific lymph node enlargement. Healing of these lymph nodes finally leads to their calcification.
You have mentioned that there is a single lymph node present in para-tracheal region measuring upto one cm.
You should consult your doctor in case you have chest symptoms like cough
, breathlessness, sputum, fever
I hope my answer is of help to you.
