Abstract
We present a 67-year-old man with allergic bronchopulmonary aspergillosis (ABPA), whose chest computed tomography (CT) scans showed localized circumferential bronchial wall thickening in the right main bronchus to middle truncus. Chest CT scans showed high-attenuation mucus in the right B(8) bronchus. Bronchoscopy showed narrowing of the right main bronchus and inspissated mucus plugging in the right B(8) bronchus. Histological examination of the right main bronchus revealed bronchial inflammation with numerous neutrophils and plasma cells. Treatment with corticosteroid and antifungal agents resulted in resolution of the symptoms and right bronchial lesions. The clinical course may indicate that the bronchial lesions were associated with ABPA.
