Normal PFTs in early asbestosis

What happened?
CXRs from the last 5 years were reviewed and showed plaques above the left and right hemidiaphragms. Tenting of the right diaphragm was first noted 4 years ago. There was evidence of early basilar fibrosis.

CT scan of the chest showed (B) pleural plaques noted, more on the left and early peripheral fibrosis.

PFT are normal.
