Isolated Streptococcus intermedius pulmonary nodules

Abstract

Streptococcus intermedius, a member of the Streptococcal anginosus group of alpha-hemolytic streptococci, remains a notable infectious agent causing necrotizing pneumonia and abscesses. We report a case of a young male with pulmonary nodules found to have Streptococcus intermedius and no other underlying hepatic or dental history who was treated with ceftriaxone and avoided surgical intervention. A review of the literature reveals cases that are typically treated with a combined surgical and medical approach. These same cases often involve middle aged to elderly individuals who have a past history of tobacco use, alcoholic liver cirrhosis and/or poor dentition. This case stands out given the patient's atypical presentation.
