Lemierre's Syndrome: A Neglected Disease with Classical Features

Area of Science:

• Medicine
• Infectious Diseases
• Critical Care

Background:

• Lemierre's syndrome, also known as the forgotten fever, is a rare thrombophlebitis of the internal jugular vein.
• It typically follows a bacterial infection, often originating in the head or neck, and can lead to severe complications.

Purpose of the Study:

• To present a case of Lemierre's syndrome in a young, immunocompetent male.
• To highlight the diagnostic challenges and management of this rare but serious condition.

Main Methods:

• Case report detailing clinical presentation, diagnostic imaging (ultrasound, CT), and microbiological findings.
• Review of treatment protocols including antibiotics and anticoagulation.

Main Results:

• A 23-year-old male presented with septic shock secondary to internal jugular vein thrombosis and septic pulmonary emboli.
• Blood cultures identified Fusobacterium necrophorum as the causative agent.
• Successful treatment with antibiotics and anticoagulation resulted in patient recovery.

Conclusions:

• Lemierre's syndrome, though rare, must be considered in patients with severe sepsis and neck/head infections.
• Early diagnosis and aggressive management are crucial for favorable outcomes.
• Fusobacterium necrophorum is a significant pathogen in Lemierre's syndrome.
