Simple silicosis

Case contributed by Dr Hani Salam


Occupational exposure with dyspnea.

Patient Data

Age: 55-year-old
Gender: Male

Chest X-ray

Right apical ill-defined opacity.


CT Chest

Multiple small nodules that are upper lobe predominant. No calcified medistinal lymph nodes.

Case Discussion

The patient gave a history of exposure to silica particles, as an occupational exposure in the past.

The findings of innumerable small nodules with predominant upper lobes affection, associated with the provided history of occupational exposures make silicosis (classic and simple) the most probable diagnosis, though coal workers' pneumoconiosis and talcosis could give very similar radiological findings.
