Question: what percentage of patients with the following scenario should get a bronchoscopy biopsy to view the pathology to best determine diagnosis? The first Doctor did not find bronchiectasis but I don’t think they considered the exudative form of cellular bronchiolitis. Now patient is getting a second opinion. Scenario: patient had an aspiration event with subsequent findings: Clinical findings: itchiness in lungs, shortness of breath (no wheezing or coughing). Radiological findings: a number of granuloma nodules in the lower left lungs and non-solidified nodules in the lower right lungs were found with tree in bud and signet ring signs in the lower lungs. As for treatment, what are the most effective options given today?
