Lemierre's Syndrome: A Case of Life-Threatening Infection From Family Medicine Practice

The use of antibiotic therapy has led to a major transformation in medicine with a substantial reduction in mortality. Due to the adverse effects associated with inappropriate antibiotic use, antibiotic stewardship interventions have been promoted to improve antibiotic prescription. However, delayed antibiotic therapy, when clinically needed, may result in increased morbidity. Here, we report the case of a previously healthy young man with an untreated acute upper respiratory infection for two weeks, who presented with headache and fever. Physical examination suggested meningitis as evident by neck stiffness and positive Kernig sign. Purulent tonsilitis was also noted. Laboratory findings showed leukocytosis and elevated inflammatory markers. The patient underwent a computed tomography scan to rule out space-occupying lesions prior to lumbar puncture. The scan revealed thrombophlebitis of the left internal jugular vein that extended to the dural venous sinuses. Magnetic resonance imaging confirmed the intracranial dissemination of the disease. Such findings conferred the diagnosis of Lemierre's syndrome. The patient was admitted to the intensive care unit where he received systemic anticoagulation and prolonged intravenous antibiotics. He developed a good response and was discharged with no residual deficits after six weeks of hospitalization. Lemierre's syndrome is a serious infection that develops after a pharyngeal infection. Considering the high mortality rate of untreated Lemierre's syndrome, physicians should keep a high index of suspicion for this condition when they encounter a patient with upper respiratory tract infection with clinical or radiological findings consistent with internal jugular thrombophlebitis.
