Lemierre's syndrome by Bacillus circulans, Fusobacterium nucleatum and Staphylococcus aureus with involvement of the internal and external jugular vein.

INTRODUCTION: Lemierre's syndrome refers to the septic thrombophlebitis of the internal jugular vein, secondary to a pharyngeal infection. Although it mainly affects the internal jugular vein, isolated cases have been described of involvement of the external jugular vein. The main etiological agent is Fusobacterium necrophorum. CASE REPORT: A 27-year-old male, previously healthy, presented with a 7-day history of sore throat and fever. He was diagnosed with Lemierre's syndrome, coinfection by Bacillus circulans, F. nucleatum and Staphylococcus aureus with an atypical presentation due to the involvement of the external jugular vein and the internal jugular vein.
CONCLUSIONS: As far as we are aware, we present the first case of Lemierre's syndrome with these characteristics. GERMS.
