A Case of Lemierre Syndrome

Abstract

Lemierre syndrome is a rare but potentially life-threatening septic condition, most commonly caused by Fusobacterium necrophorum.
We report the case of a 36-yearold man presenting with high fever, cervical lymphadenopathy, and respiratory manifestations shortly after a recent dental extraction. Imaging revealed thrombophlebitis of the internal jugular vein and septic pulmonary emboli, and microbiological investigations identified Fusobacterium necrophorum. Early recognition of the syndrome and initiation of empiric intravenous antibiotic therapy resulted in a favorable clinical outcome. This case underscores the importance of considering Lemierre syndrome in patients with oropharyngeal infection and signs of sepsis.
