I have read your concerns and i think you might be suffering from Endobronchial tuberculosis
. It is a form of tuberculosis which may present with normal chest x-ray but CT scan
Thorax and bronchoscopy
shows features suggestive of disease, as is in your case. The treatment is with the anti-tubercular drugs for 6months, if treated for the first time. it is a completely curable disease.
Wait for your pathology report, i feel it will be suggestive of tuberculosis.
Wish you a good health and success.
