Background. Bronchoaspiration of a foreign body is rare in adults. Adult bronchoaspiration patients often develop minor symptoms. Therefore, it takes time to diagnose them as having bronchoaspiration. We herein report an adult patient who aspirated a peanut in his bronchus with ABPA-like chest shadows. Case. A 69-year-old man presented to our hospital in June with persistent cough and sputum from April, 201X. Chest plain CT showed central bronchiectasis with mucoid impaction and infiltrates in the peripheral lung. From the characteristic CT findings, we initially suspected ABPA as his diagnosis. However, further examinations denied this possibility. Reassessment of the chest HRCT revealed a foreign body in his bronchus and led us to perform bronchoscopy. A bronchoscopic examination revealed a foreign body covered with pus in the lower right lobe ports, which was later revealed to be a peanut. After extraction of the foreign body, his symptoms improved, and the chest CT findings disappeared. Conclusion. We encountered a unique case presenting with ABPA-like shadows due to long-term peanut aspiration.
