Lemierre Syndrome: Incidental Finding of Forgotten Fatal Disease as a Complication of Ludwig's Angina.

Lemierre syndrome (LS) is a rare, life-threatening complication of oropharyngeal infections associated with septicemia and internal jugular thrombosis. Internal jugular vein thrombosis is an uncommon disease associated with central vein catheterization, intravenous drug abuse, hypercoagulability, trauma to the neck, infection, ovarian hyperstimulation syndrome (OHSS), and systemic infections. Here, we highlight a case of a 62-year-old women who presented progressively worsening neck swelling for three weeks, shortness of breath, and fever for four days. Her sepsis due to Ludwig's angina was accompanied by septic pulmonary embolism and internal jugular vein thrombosis in keeping with a diagnosis of Lemierre syndrome. For this presentation of Lemierre syndrome, the treating physicians recommended surgical excision and drainage, followed by intravenous antibiotics and subcutaneous anticoagulation to treat septic emboli of the lungs and internal jugular veins. Sadly, after being informed about the procedure, the patient refused to consent, and four days later, she passed away. It is essential to remember that early detection and aggressive treatment may significantly impact prognosis and outcome.
