Lemierre’s Syndrome: Rare, but Life Threatening—A Case Report withStreptococcus intermedius

Abstract

Lemierre’s syndrome (LS) is a rare, but a life-threatening complication of an oropharyngeal infection. Combinations of fever, pharyngitis, dysphagia, odynophagia, or oropharyngeal swelling are common presenting symptoms. Infection of the lateral pharyngeal space may result in thrombosis of the internal jugular vein, subsequent metastatic complications (e.g., lung abscesses, septic arthritis), and significant morbidity and mortality. LS is usually caused by the gram-negative anaerobic bacillusFusobacterium necrophorum, hence also known as necrobacillosis. We present a case of LS caused byStreptococcus intermedius, likely secondary to gingival scraping, in which the presenting complaint was neck pain. The oropharyngeal examination was normal and an initial CT of the neck was done without contrast, which likely resulted in a diagnostic delay. This syndrome can be easily missed in early phases. However, given the potential severity of LS, early recognition and expedient appropriate antimicrobial treatment are critical.S. intermediusis an unusual cause of LS, with only 2 previous cases being reported in the literature. Therefore, an awareness of the myriad presentations of this syndrome, which in turn will lead to appropriate and timely diagnostic studies, will result in improved outcome for LS.
