Lemierre syndrome from a neck abscess due to methicillin-resistant Staphylococcus aureus

Lemierre syndrome is characterized by acute septic thrombophlebitis of the internal jugular vein (IJV) that develops after an oropharyngeal infection, and can be complicated by septic emboli to lungs and other organs. The most frequent causative agent is Fusobacterium necrophorum, an anaerobic bacillus found in normal oropharyngeal flora. Staphylococcus aureus has emerged as a cause of Lemierre syndrome in the last decade. We report a case of a 24-year-old man who developed septic IJV thrombosis and necrotizing pneumonia due to S. aureus from an infected hematoma in the right sternocleidomastoid muscle. Antibiotics are the mainstay of therapy with few cases needing anticoagulation. A good outcome is dependent upon an awareness of the condition, a high index of suspicion, and prompt initiation of antibiotic therapy. Recognition of S. aureus as a cause of Lemierre syndrome can guide the choice of initial antibiotics to cover this virulent pathogen. (c) 2013 Elsevier Editora Ltda. All rights reserved.
