• Allergic bronchopulmonary aspergillosis: Hypersensitivity response associated with asthma and cystic fibrosis that can lead to bronchiectasis and eosinophils
• Bronchiectasis = Chronic productive cough + linear atelectasis + thickened airways and irregular cystic opacities
• Key idea: Treatment is months of treatment with itraconazole + oral corticosteroids
• Cystic fibrosis –> Also associated with bronchiectasis and ABPA, but patient would have history of recurrent sinopulmonary infections, fat soluble vitamin deficiency, etc.
• Alpha-1 antitrypsin deficiency –> Lungs and liver problems with family history
