Lemierre Syndrome in the Setting of Bacteremia and Atypical Pneumonia: A Case Report.

Lemierre syndrome is an uncommon condition that typically presents with oropharyngeal infection and subsequent thrombophlebitis of the internal jugular veins. The syndrome is associated with septic emboli, frequently of the lungs, as well as Fusobacterium necrophorum bacteremia. Here, we report a case of Lemierre syndrome in the setting of an atypical pulmonary pathology. During the patient's clinical course, a peritonsillar abscess was identified, as well as associated septic emboli and superimposed Mycoplasma pneumoniae in the setting of F. necrophorum bacteremia. Prompt imaging and antibiotic treatment, in addition to an incision and drainage of the peritonsillar abscess, allowed for the patient to be medically optimized for discharge home with intravenous and oral antibiotics. Early recognition of this rare syndrome can help guide treatment and promote positive outcomes for patients affected by Lemierre syndrome.
