AbstractAn 86-year-old woman was admitted for the investigation of atelectasis of the upper lobe of her right lung with a mass shadow in the hilum (Golden S sign). Chest computed tomography revealed swollen connective tissue around the right bronchus, and needle aspirate grew Bifidobacterium longum and Veillonella species. She was diagnosed with peribronchial connective tissue infection, and her condition improved with antibiotics. Although this sign is strongly suggestive of malignant disease, benign disease should be considered in the differential diagnosis. Pulmonary infection caused by Bifidobacterium longum is extremely rare; however, clinicians should consider it as a possible cause of pulmonary infections.
