List five parenchymal changes seen in patients with sarcoidosis.

1. Reticulonodular infiltrates extending from the hilar regions
2 Alveolar sarcoidosis (i.e., multifocal, ill-defined foci of airspace disease, often associated with obvious hilar adenopathy)
3. Large nodular sarcoidosis
4. Miliary sarcoidosis
5. Severe coarse fibrosis radiating from the hila, bulla formation, mycetoma formation, and bronchiectasis; suggestive of progression to more severe disease (seen in only 5%-10% of patients)
