Lemierre syndrome involving external jugular vein.

Abstract

A 74-year-old woman with a week-long history of cold symptoms was diagnosed with Lemierre syndrome that involved her left external jugular vein. The patient was successfully treated with 4 weeks of antibiotics and anticoagulant treatment. Typical cases of Lemierre syndrome involve only the internal jugular vein. The external jugular vein is anatomically distant from the pharyngolaryngeal space and usually does not receive blood or lymphatic flow from there. Thus, Lemierre syndrome ordinarily does not involve the external jugular vein and clinical characteristics of external jugular vein-involving Lemierre syndrome have not been uncovered, mainly due to its rarity. Based on our review, it would not much differ from those of typical cases. Considering the potential severity and mortality, more attention should be paid to this potentially fatal disease that may demonstrate atypical manifestation, as shown in this case. Accumulation of cases would be needed for further understanding.
