Simple silicosis

Case contributed by Dr Hani Makky Al Salam


Occupational exposure with dyspnea

Patient Data

Age: 55 years
Gender: Male

Chest X-ray


Right apical ill-defined opacity.

CT Chest


Multiple micronodules, upper lobe predominant. No calcified mediastinal 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 micronodules with predominant upper lobe affection, associated with the provided history of occupational exposures make simple silicosis the most probable diagnosis, though coal workers' pneumoconiosis and talcosis could give very similar radiological findings.
