Lemierre's syndrome from odontogenic infection causing thrombophlebitis within the external and internal jugular veins—A case report

Abstract

AbstractLemierre's syndrome is a rare but potentially life‐threatening condition primarily caused by anaerobic bacteria within in the oropharyngeal region. It largely affects otherwise healthy individuals, following an oropharyngeal infection, leading to sepsis and thrombophlebitis of the internal jugular vein. Management can involve a prolonged course of antibiotics, exclusion of the source of infection, surgical drainage and anticoagulant therapy. This case report describes a rare presentation of this condition causing thrombosis within the external jugular vein and significant sepsis in an otherwise healthy 41‐year‐old male. He presented with severe neck pain and trismus, and the source of the infection was deemed to be an infected mandibular molar. The patient has undergone a full recovery following intravenous antibiotics, anticoagulation and later extraction of the offending tooth. Our aim is to educate clinicians on the importance of this uncommon but clinically significant condition, that is increasing in prevalence and can lead to significant morbidity.
