Post-traumatic Lemierres Syndrome: A rare presentation secondary to mandibular fracture

Lemierre's Syndrome is a rare phenomenon with a low prevalence and is characteristically seen in patients with an oropharyngeal infection that is complicated by thrombophlebitis of the internal jugular vein and secondary septic emboli. We present the case of a 16 year old previously well male who was diagnosed with a rare case of Lemierre's syndrome secondary to a mandibular fracture. Blood tests and radiological imaging confirmed the diagnosis, with CT scan of the patients head and neck revealing a right mandibular fracture with abscess formation, bilateral parapharyngeal abscesses, bilateral internal jugular vein thromboses, left sigmoid sinus thrombosis, cavernous sinus thrombosis, post septal orbital cellulitis with enhancing infraorbital collections and a subdural empyema overlying the left tentorium cerebelli. The treatment is usually non-operative with antibiotics and in some instances surgical drainage. In this case a combination of surgical drainage for source control and antibiotics were used. Unfortunately, despite an initial improvement in the patient's clinical status the patient died. This is the first case of Lemierre's syndrome secondary to blunt facial trauma reported in the scientific literature. This case highlights the importance of clinicians having a high degree of suspicion of Lemierre's syndrome when a patient presents with typical clinical features following facial trauma.
