High-resolution CT reveals innumerable small nodules in bilateral upper lobes with eggshell calcification of hilar lymph nodes. Pulmonary function tests show reduced FVC and FEV1 with normal FEV1/FVC ratio. No fever or night sweats reported. Which diagnosis best explains these findings?
- A)Coal workers pneumoconiosis
- B)Sarcoidosis
- C)Berylliosis
- D)Asbestosis
