Hi doctor,

My mother's X-ray indicated the following results: hyperinflated right mid and lower zones, atelectasis, fibrosis, parenchymal nodular opacities, and patchy consolidation of the right upper lobe and the entire left lung features suggestive of sequelae and pulmonary tuberculosis. Our doctor suggested HRCT of the lungs and chest. I have attached the reports. Her QuantiFERON TB gold gave a positive result of 0.99 IU/ml. The sputum (direct smear) test showed a negative result. Should I be concerned?



Welcome to

From the reports attached (attachment removed to protect the patient's identity), the findings indicate a past history of tuberculosis. Your mother's lung shows scarring and fibrosis due to a healing mechanism known as tuberculosis sequelae. Is there any history of tuberculosis or BCG (bacillus Calmette Guerin) vaccination in childhood?
