Insufficient initial treatment but good recovery after diagnosis of pulmonary actinomycosis

Abstract

Abstract Actinomycosis is an infrequent invasive bacterial disease. Although multiple different clinical features of actinomycosis have been described, pulmonary actinomycosis (PA) is a rare but challenging diagnosis and complete cure to make. Here we report the case of a 41-year-old Asian woman who had a mass-like consolidation in the right middle lung field. The lung lesion was exacerbated after initial treatment. After diagnosis of PA, thoracoscopic resection combined with intravenous and oral penicillin made a good recovery.
