Lemierre syndrome: a diagnostic dilemma in paediatric patients

Lemierre's Syndrome in the 21st Century: A Literature Review

Lemierre's syndrome is a rare, life-threatening complication of an acute oropharyngeal infection. It is generally characterised by pharyngitis secondary to Fusobacterium necrophorum, causing thrombophlebitis of the internal jugular vein and sepsis, with subsequent formation of septic emboli that can rapidly spread to different organ sites. The condition is associated with high mortality if treatment with antibiotics is delayed, and recent evidence suggests that patients are at significant risk of in-hospital morbidity and long-term neurological sequelae. Although it is agreed that antibiotics are the mainstay of treatment, there is currently no consensus on the use of anticoagulation in the condition. This review article aims to summarise our current understanding of Lemierre's syndrome with regard to its definition, epidemiology, microbiology, presentation, diagnosis, and treatment.
