Can TB lympadentitis cause lung scarring without having pulmonary tb? Chest xray show only enlarged gland.

1 doctor agrees

In brief: Highly unlikely

TB lymphadenopathy is initiated when macrophages carry the bacillus from a pulmonary alveolar focus to the lymph node which then enlarges, suppurates and ruptures into an adjacent blood vessel.
So it is virtually impossible to have pulmonary nodes involved without having pulmonary infection first.

other conditions, e.g. sarcoidosis, can cause abnormal lymph nodes on chest xray, woth normal appearing lungs
