[|Human|] i had PTB in 2007 and had 6 months of treament. after the treatment the doctor said i am cured from it. i was just wondering why on my recent xray they found suspicious densities on the upper right lobe of my lungs. i am 24 years of age and i had done my treatment of PTB 4 years ago.
[|AI|]  Hi welcome to Chat Doctor..... Here you are having density in lung in upper lobe.... If it is not clear in x-ray then CT scan can be done.... There can be lots of cause for opacity... But common one pneumonia and tuberculosis is there if associated with fever... For that sputum examination done by gram and acid fast stain to rule out these two condition.... The density can also be there like hematoma like condition... Your subsequent resp examination also has to be carried out.... Consult pulmonologist for your resp examination and investigation... Take care. Chat Doctor.
