Thanks for your question on Healthcare Magic.
I can understand your concern.
First of all, you should get done liver function test to rule out drug induced
jaundice because anti tubercular drugs are known to cause
hepatitis and your symptoms likelike nausea, vomiting and yellowish discoloration of eyes are suggestive of jaundice.
About your x ray report, Heterogeneous opacity means, irregular lesions and this is commonly seen with
lung infection. Upper lobe lesions are common with tuberculosis. So
radiologist advised to see for tuberculosis.
Since you are already diagnosed case of tuberculosis, this lesions on chest x ray are mostly due to healing from tuberculosis.
Trachea midline is normal. Nothing to worry about this.
R/O means Rule out. Radiologist wants your primary doctor to rule out (R/O) tuberculosis in your case. So he writes r/o PTB (
pulmonary tuberculosis).
No need to worry as your follow up sputum is negative for tuberculosis.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
