We present a case of a patient with Lemierre's syndrome caused by Fusobacterium 
necrophorum who developed a right frontal lobe brain abscess. We summarise the 
epidemiology, microbiology, pathogenesis, clinical presentation, diagnosis, 
complications, therapy, and outcomes of Lemierre's syndrome. F necrophorum is 
most commonly associated with Lemierre's syndrome: a septic thrombophlebitis of 
the internal jugular vein. Patients usually present with an exudative 
tonsillitis, sore throat, dysphagia, and unilateral neck pain. Diagnosis of 
septic thrombophlebitis is best confirmed by obtaining a CT scan of the neck 
with contrast. Complications of the disease include bacteraemia with septic 
abscesses to the lungs, joints, liver, peritoneum, kidneys, and brain. Treatment 
should include a prolonged course of intravenous beta-lactam antibiotic plus 
metronidazole.
