Due to its adaptive traits and antibiotic resistance, E. faecium has evolved as a worldwide hospital-associated pathogen, especially vancomsycin-resistant Enterococcus faecium (VREfm). Pneumonia caused by VREfm is quite rare in clinical settings, and optimal treatment has not yet been determined. Here, we present a case of nosocomial VREfm pneumonia with lung cavitation following adenovirus infection, which was successfully treated with linezolid and contezolid.Keywords: vancomycin-resistant enterococcus, Enterococcus faecium, pneumonia, contezolid
