[Lemierre's syndrome. An unusual variant]

Area of Science:

• Infectious Diseases
• Microbiology
• Otolaryngology

Background:

• Lemierre's syndrome, or postanginal septicaemia, is an uncommon sequela of oropharyngeal infections.
• Fusobacterium necrophorum is the most frequent causative agent identified in classical presentations.
• The condition typically manifests in young, healthy individuals with symptoms including fever, neck swelling, and pain, often leading to septic pulmonary emboli.

Observation:

• This report details an atypical case of Lemierre's syndrome in a 12-year-old patient.
• The primary site of infection in this case was identified as the middle ear, deviating from the usual oropharyngeal origin.

Findings:

• The middle ear infection served as the unusual primary focus for the development of Lemierre's syndrome.
• This presentation challenges the typical understanding of the syndrome's origin.

Implications:

• This case broadens the spectrum of potential primary infection sites for Lemierre's syndrome.
• Clinicians should consider otogenic sources in the differential diagnosis of Lemierre's syndrome, especially in pediatric cases.
• Further research may elucidate the specific mechanisms allowing middle ear infections to precipitate this severe condition.
