<s>[INST] Good Day. I got my chest x-ray and diagnose that i have a pneumonia, right lower lung. They seen on my chest xray that there is haziness in my right lower lung. Doc, what does it mean? Is there a possibility that the impression is correct or is pneumonia can lead to tuberculosis? Please help, am paranoid of this pulmonary tuberculosis. Thanks, Lilou [/INST] Hello dear, thanks for your question on HCM. Tuberculosis  is more common  in upper lobes and less common  in lower  lobes. TB bacilli  grow more faster and have higher affinity  for oxygen. And in lungs, upper lobes have highest oxygen concentration. So Tuberculosis  affects upper lobes more. It can affect lower lobes in diabetes  and His infection. So in my opinion get done screening  for diabetes  and His.  If both are negative  then Tuberculosis  is less likely  in your case. Also get done sputum examination  for Aug (acid  fast bacilli-TB bacilli). If this is normal  then no need to worry for Tuberculosis. You are having  mostly  bacterial pneumonia. So start treatment accordingly. </s>
