I am 56 years old female, non smoker. No known lung exposures or infections. Having sudden onset dyspnea on exertion. CXR shows large lung volumes with fibrosis in apices suspicious for emphysema. Pulm function tests show mild obstructive lung disease. CT shows mild bi apical pleural parenchymal fibrosis. I have to wait a month to see a pulmonologist. Can you tell me if I should be worried about a diagnosis of pulmonary fibrosis? Is that a possibility? Thank you.
