[A case of Fusobacterium necroforum sepsis]

A 26-year-old man was admitted to our hospital with a 10-day history of sore throat, high fever, and right knee joint pain. On physical examination, the pharynx was considerably inflamed, and the right knee joint was swollen and extremely tender. Chest radiography showed multiple, bilateral nodules and masses with pleural effusions. Fusobacterium necorforum grew from samples of blood, pleural effusion, and pus taken from the knee joint. The patient was treated with intravenous clindamycin, ventilatory support, and continuous chest and knee joint drainage. His condition progressively improved and he was discharged on the 66th hospital day. A disease caused by an oropharyngeal infection with secondary suppurative thrombophlebitis of the internal jugular vein, and complicated by multiple metastatic infections is called postanginal septicemia, or Lemierre syndrome. Before the discovery of antibiotics, this disease usually was fatal. The widespread use of antibiotics for treat oropharyngeal infections may have caused a number of reported cases. Lemierre syndrome is an uncommon complication of oropharyngeal infection, and it may be fatal if diagnosis is delayed. Careful attention must be directed to patients with oropharyngeal infection who have signs and symptoms that suggest metastatic infection.
