A 72-year-old male with 30 years of occupational asbestos exposure installing shipyard insulation presents with progressive exertional dyspnea. Vital signs show BP 138/82 mmHg, HR 92/min, RR 22/min, SpO2 88% on room air. High-resolution CT chest demonstrates bilateral lower lobe interstitial fibrosis and calcified pleural plaques. Pulmonary function testing shows reduced DLCO at 62% predicted. He denies constitutional symptoms or smoking history. Which diagnosis best explains these findings?

  1. A)Coal workers pneumoconiosis
  2. B)AsbestosisGABARITO
  3. C)Mesothelioma
  4. D)Idiopathic pulmonary fibrosis
  5. E)Silicosis
