Background: Here we report a rare case of allergic bronchopulmonary aspergillosis (ABPA), which has been managed with repeated antibiotics for 2 years under the diagnosis of recurrent pneumonia. Results: 37 years old women has suffered from persistent sputum, cough and dyspnea since 4 years ago. Antibiotics were prescribed repeatedly because chest X-ray showed pneumonic consolidation for 2 years. She was referred because her symptoms and abnormal chest X-ray findings were not improved even with the IV antibiotics. She had the history of childhood asthma. However she has not been managed with anti-asthma medication, because she was free from asthma symptoms since 10 years old. Chest X-ray showed pneumonic consolidation in right upper lung and Left lower lung with bronchiectasis in both mid to lower lung zones. Laboratory tests revealed a leukocyte count of 5,980/uL (eosinophil 33.1%). A skin prick test showed positive results to Dermatophagoides farina (3+), Dermatophagoides pteronyssinus (4+), and Aspergillus fumigates (3+). PFT showed restricted change: FVC 2.48L (69.2% predicted), FEV1 1.77L (56.8% predicted), FEV1/FVC 71.1%. Bronchodilator test was positive. Chest CT showed central bronchiecatsis with high attenuation mucus, and multifocal tubular/varicose bronchiectasis in both lungs, central and upper lung predominance The level of serum total IgE was 4,032 kU/L, and specific IgE to Aspergillus was 5.49 kUA/L (Class 3). Systemic steroid was administered under the impression of ABPA, and her symptoms and pneumonic consolidation were resolved. The level of total IgE was decreased to 783 kU/L after treatment with systemic steroid. Conclusions: In case of ABPA, early diagnosis and adequate treatment are very important to prevent development of fibrodestructive changes.
