It is often presented with sepsis, sore throat, fever, neck pain, internal jugular vein thrombophlebitis/thrombosis, and septic emboli. The bacteria that are usually associated with the disease are Fusobacterium species, but it is also associated with Staphylococcus, Streptococcus, and other bacterial species. The diagnosis of Lemierre's syndrome is made based on evidence of septic thrombophlebitis, preceding oropharyngeal infection, and positive culture. Treatment usually consists of antibiotics directed toward the causative organism. The use of anticoagulation, although controversial, is shown to be beneficial by several studies. We describe a middle-aged patient who presented with a sore throat, neck pain, and dysphagia. Imaging of the neck and chest revealed right jugular thrombosis along with septic emboli in the lungs. The culture of the blood and pus drained from the peritonsillar abscess grew Streptococcus anginosus. In this study, we have illustrated the effective management of Lemierre's syndrome with antibiotics, anticoagulants, and needle aspiration of abscess.
