Lemierre's Syndrome: A Neglected Disease with Classical Features

We report the case of a previously healthy, immunocompetent 23-year-old male who presented to the Emergency Department with general malaise, difficulty in breathing, fever, and chest pain. He reported a two-week history of progressively worsening sore throat that he presumed to be a viral infection and thus initially neglected. However, when his condition deteriorated, he was admitted to hospital acutely unwell and in respiratory distress. He quickly developed septic shock requiring intensive care admission for inotropic support. Ultrasound and CT imaging revealed internal jugular vein thrombosis with associated septic emboli reaching the lungs to form bilateral cavitations and consequently pleural effusions. Blood cultures were positive for Fusobacterium necrophorum. Based on these findings, a diagnosis of Lemierre's syndrome was made. The patient was treated with appropriate antibiotics and anticoagulation and gradually recovered. He was discharged 20 days after admission with advice to complete a six-week course of antibiotics.
