An unusual pathogen for a liver abscess in a human immunodeficiency virus-infected individual

Pyogenic liver abscesses are rarely encountered in HIV-infected patients living outside of temperate climates and are usually polymicrobial in nature, with a majority of the pathogens arising from gastrointestinal flora. We describe the second case of a liver abscess in an HIV-positive individual that was caused by methicillin-resistant Staphylococcus aureus (MRSA), most likely due to a partially treated community-acquired MRSA skin abscess. The liver abscess was successfully managed by percutaneous drainage and intravenous antibiotics. This case underlines the ubiquitous nature of community-acquired MRSA and its possible unusual presentations in immunocompromised hosts.
