[|Human|] My dad is 84 years old and had persistent cough for quite sometime. Recently after doing and x-ray it was found that he has some irregular nodularities in both the lungs and also has coarse bronchal vasculature and thick bronchial walls. Is anything serious? Thanks
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your fathers situation and problem. Irregular polarities and prominent BVM (bronchovascular marking) in both lungs, on chest x-ray is seen in Interstitial Lung disease (OLD). He is also having1. Old age2. Chronic cough. So better to consult pulmonologist and get done1. Clinical examination of respiratory system. 2. CT thorax3. PUT (pulmonary function test). CT thorax will be more informative and diagnostic for OLD. PFT will also helpful in determining decrease in lung functions. So consult pulmonologist and discuss all these and first diagnose him self and then start appropriate treatment.
