Ct scan result ptb both upperlobes, pleural thickening, pleuroparenchymal fibrosis both upperlobe. no treatment done. is this serious?

Yes: Need sputum AFB and culture. Need treatment if positive with multiple TB medications and respiratory isolation. If negative but PPD positive will need treatment for latent PTB

No: You had an infection in your lungs that resolved but left scars. As a radiologist, I see this often and will generally comment on it but know it is not anything that needs attention. That being said, if you have a positive test for TB, you should consult your doctor.
