Hi & Welcome. Incomplete data like age, gender, purpose of doing chest x ray, any associated symptoms like cough, fever, hemoptysis, weight loss, smoking, etc??? Based on the report of the chest x ray, you have small sized nodular densities which could be due chronic infections like tuberculosis, fungal infections like aspergillosis or histoplasmosis. Other common conditions which may give rise to a similar findings include a benign tumor called hamartoma or a cancer of the lungs. In view of the above you need to have further imaging studies like CT scan to find out the exact cause. Hope this answers your query.
