<s>[INST] hi doc, my husband just had his xray and the results were Suspicious both apical densities, =lordtodic view apical density he has no issue of having TB or PTB Do you think his allergies from dust pollens etc, might have caused these? Whenever he smelled dust he continually sneeze [/INST] Hello, Welcome to Chat Doctor, Most common cause for apical lung densities are Pulmonary tuberculosis and pneumonia leading to consolidation of lung. Pulmonary tuberculosis more commonly involves apical lung fields. In bronchial asthma you will see nothing on x-ray. Asthma is a condition of hypersensitivity of airway tract due to allergy to dust, pollen and mites. Asthma is diagnosed based on the clinical symptoms of the patient. Hope I have answered your doubt. Thank you. </s>
