[Imaging findings in Lemierre syndrome]

Area of Science:

• Infectious Diseases
• Radiology
• Vascular Surgery

Background:

• Lemierre syndrome is a rare but severe complication of pharyngotonsillitis.
• It involves septic thrombosis of the internal jugular vein, often caused by anaerobic bacteria.
• The condition typically affects young, previously healthy individuals.

Observation:

• This report details three recent cases of Lemierre syndrome.
• The cases highlight the progression from untreated pharyngotonsillitis to severe complications.
• Clinical presentation and diagnostic challenges are discussed.

Findings:

• Cervical and thoracic computed tomography (CT) are invaluable diagnostic tools.
• CT imaging effectively visualizes internal jugular vein thrombosis and pulmonary abscesses.
• Early identification of septic thrombosis is key.

Implications:

• Prompt diagnosis and treatment of Lemierre syndrome can prevent life-threatening outcomes.
• The study underscores the importance of considering Lemierre syndrome in patients with severe throat infections and respiratory symptoms.
• Enhanced imaging protocols are vital for timely intervention and improved patient prognosis.
