Lemierre’s Syndrome with Facial Vein Thrombosis and Pulmonary Septic Emboli: A Case Report

Introduction: Lemierre’s syndrome (LS) is a rare and serious condition that often affects school-aged children, adolescents, and healthy young adults. It is defined as an oropharyngeal infection with secondary septicemia, internal jugular vein thrombosis, and septic emboli. Rare cases of atypical LS in which thrombosis occurs in other locations have been reported. Case Presentation: We presented a case of an adolescent with fever, sore throat, and neck tenderness. Physical examination revealed acute pharyngitis and bilateral small cervical lymph nodes. Rapid antigen group A Streptococcus and viral serologic tests were negative. Complete hemogram and blood biochemical analysis showed leukocytosis and elevated serum C-reactive protein (CRP). Cervical computerized tomography (CT) scan revealed a heterogeneous right tonsil and small cervical lymph nodes. The chest radiograph was normal. After admission, the adolescent started complaining of dyspnea and thoracic pain and had a painful small cervical right mass. In the thoracic CT angiography (CTA), several pulmonary septic emboli were apparent throughout the pulmonary parenchyma. Cervical Doppler ultrasound showed right facial vein thrombophlebitis, later confirmed in a CTA. Thromboses in other locations, including the internal jugular vein, were excluded, as well as cervical abscesses. The patient was successfully treated with intravenous antibiotic therapy and anticoagulation. Discussion: To this date, no reports of LS presenting with isolated thrombosis of the facial vein have been described in pediatric patients. We highlighted the importance of early recognition of LS and its atypical variants. Pediatric international guidelines regarding its management and treatment would also greatly affect the outcome of these patients.

Lemierre's syndrome: current perspectives on diagnosis and management

This is a systematic review of cases with Lemierre’s syndrome (LS) in the past 5 years. LS is characterized by sepsis often evolving after a sore throat or tonsillitis and then complicated by various septic emboli and thrombosis of the internal jugular vein. Symptoms include sepsis, pain, and/or swelling in the throat or neck, as well as respiratory symptoms. Laboratory findings show elevated infectious parameters and radiological findings show thrombosis of the internal jugular vein and emboli in the lungs or other organs. The syndrome is often associated with an infection with Fusobacterium necrophorum. We found a total of 137 cases of LS, of which 47 were infected with F. necrophorum and others with Staphylococcus and Streptococcus. Complications of this rare but severe disease included osteomyelitis, meningitis, and acute respiratory distress syndrome. Mortality was extremely high in the pre-antibiotic era but has diminished with the advent of antibiotics. This review showed a mortality rate of only 2% of which none of the cases involved fusobacteria. Duration of treatment varied; a 4–6-week course of carbapenem or piperacillin/tazobactam in combination with metronidazole was optimum. Other treatment options included anticoagulants in 46% of cases, which is unwarrantedly high, as to date, no evidence of the positive effects of anticoagulants in LS exists. Only two cases had ligation of the internal jugular vein performed. This review confirms the rare, but severe aspects of LS. Mortality from LS in this day and age appears to be low, however the syndrome is difficult to recognize, and still requires the full attention of the clinician.
