Bronchial Wall Thickening

The bronchial wall thickening noted on the CT was not related to the veno-occlusive disease, but rather to the changes noted in the histologic sections shown below.

Note the hyperplastic epithelium, prominent smooth muscle, and fibrosis around this medium-sized airway. The artery to the right has a thickened media.

At higher magnification, the goblet cells are increased in number and there are many subepithelial inflammatory cells.

What is the cause of the bronchial wall thickening?
