Learnings from the case

  1. Preserved lung volumes do not exclude IPF even in the absence of emphysema.
  2. Current data support the initiation of antifibrotic treatment in IPF patients    with preserved lung volumes (FVC>80%).
  3. Despite the preserved FVC, DLCO deterioration seems to correlate better with  progression of fibrosis on HRCT.1
