CT scan shows upper zone predominant mass-like scarring with calcification and volume loss. Hilar and mediastinal lymph node calcification also noted. No cavitary changes are seen. There is a left pleural effusion.
Case Discussion
Chest x-ray and CT scan of the chest demonstrate characteristic upper zone mass-like scarring with calcification and volume loss. Hilar and mediastinal lymph node calcification is also demonstrated. Features are in keeping with silicosis and progressive massive fibrosis (PMF).
