ABSTRACT

A 70-year-old man who underwent treatment for chronic necrotizing pulmonary aspergillosis (CNPA) presented with fever, cough, and dyspnea on exertion. Chest computed tomography (CT) showed a 20-mm nodule with the subpleural region and pleural thickening in the right lower lobe. Purulent content was taken from the nodule by means of ultrasound-guided aspirations. Actinomyces naeslundii, Streptococcus intermedius, and Fusobacterium nucleatum were cultured from the suppuration. We diagnosed as pulmonary abscess by combined infection that included A. naeslundii. It was difficult to distinguish from deterioration of CNPA on chest CT. After a six-month antibiotic therapy, his chest CT was improved. A. naeslundii does not form druse, so its identification was very difficult. We encountered a rare case of pulmonary abscess caused by A. naeslundii.
