Abstract
Lemierre's syndrome (LS) is a rare and potentially life-threatening complication of an oropharyngeal infection, resulting in the presence of septic thrombophlebitis in the internal jugular vein. This condition is most commonly caused by Fusobacterium necrophorum, with a prevalence of one case per million people annually. LS is more commonly seen in adolescents or young adults, but it can also occur in children. Despite its rare occurrence, prompt diagnosis of this condition and the initiation of treatment are crucial to preventing fatal complications. In this study, we report a unique case of a previously healthy seven-year-old male with LS who presented with fever, left-sided neck pain, and swelling.
