The foreign body aspiration caused bronchiectasis, a condition where the airways are progressively destroyed and dilatated. This dilatation is very visible on this preparation as large holes on the cut surface of the parenchyme. Bronchiectasis often comes with acute purulent inflammation, which is the yellowish thing that can be seen around the bronchial tree.

If you’ve ever dissected a lung during autopsy, you’ve opened the bronchial tree with scissors (if you haven’t tried, you should!). Normally, you can only open 2/3 of the length of the bronchial tree because the last third has such a small lumen that the scissors can’t get into them. A very characteristic finding for bronchiectasis in autopsy is that you can open the ''whole'' length of the bronchial tree, because the whole tree is so dilated that the scissors can get into the lumen of even small bronchioles.
