We reported a case of Streptococcus constellatus infection, presenting as multiple pulmonary cavities, thoracic wall abscess and vertebral destruction. The 37-year-old male had recurrent fever, chest wall swelling and pain, and lower limb numbness, he had weak physical condition and previously suffered from poorly controlled diabetes and severe periodontal disease for 3 years. Definite diagnosis of Streptococcus constellatus infection was made by metagenomic next‑generation sequencing (mNGS) in abscess drainage fluid. Systemic antibiotics and thoracic wall drainage were given, and the pulmonary cavity and the thoracic intermuscular abscess were significantly decreased. Few to no study reported the disseminated infection (pulmonary cavities, thoracic wall abscess and vertebral destruction) caused by Streptococcus constellatus. This case report highlighted the importance of mNGS for accurate diagnosis, as well as the timely drainage and antibiotics for effective treatment of Streptococcus constellatus infection.Keywords: Streptococcus constellatus, pulmonary cavity, thoracic wall abscess, vertebral destruction, metagenomic next‑generation sequencing
