Other pneumoconiosis
- Silicosis is differentiated from other occupational disease like asbestosis from the history of exposure and occupational history.
Malignant diseases
- Multiple pulmonary nodules that are ≥1 cm in diameter or detected by conventional chest radiography are most likely due to metastatic disease from a malignant solid organ primary tumor [1].[2]
- Multiple pulmonary nodules that are <5 mm in diameter, juxtaposed to either the visceral pleura or an interlobar fissure, and detected incidentally, are more likely to be benign lesions, such as granulomata, scars, or intraparenchymal lymph nodes [3]
Mycobacterial infections
Fungi
- Multiple pulmonary nodules may be due to a fungal infection such as histoplasmosis, coccidioidomycosis, blastomycosis, or cryptococcosis. Invasive aspergillosis is likely in immunocompromised hosts. Nodules due to fungal infection tend to be 0.5 to 3 cm in diameter and do not have a predilection for a specific region of the lungs
Both coal workers' pneumoconiosis and silicosis may evolve into progressive massive fibrosis or conglomerate masses[5]
Parasites
- Paragonimus westermani is a fluke that is endemic in parts of China, Korea, Japan, the Philippines, and Taiwan. Humans acquire the infection by ingesting uncooked fresh water crabs or crayfish that harbor the metacercarial stage of the parasite[6]
