We report 2 cases of extensive methicillin-resistant Staphylococcus aureus (MRSA) retropharyngeal abscesses in young infants. In 1 case, the abscess was associated with a reactive thrombosis of the jugular vein. Based on the existing literature and the rapid emergence of MRSA skin and soft tissue infections, it is possible that similar severe infections will occur with increasing frequency in young infants.
