What's your diagnosis? This is not TB, I'll tell you that in advance. I'll post the correct answer in a day or three!
OK, maybe I should help you by saying that it's not TB this time ;-) I'll also add this to the original post.
Correct answer: Idiopathic pulmonary fibrosis. A chronic disease with an unknown cause. Patients usually present with a chronic dry cough, dyspnea, fatigue and rapid weight loss. The only cure is lung transplants.
