Lemierre’s syndrome: an unlikely diagnosis in a patient presenting with diarrhoea and vomiting, or maybe not?

Lemierre's syndrome is an infectious thrombophlebitis of the internal jugular vein most commonly due to <i>Fusobacterium necrophorum</i> originating from a tonsillar or peritonsillar abscess, which may cause septic emboli in the lungs.Gastrointestinal symptoms, including diarrhoea, are commoner than appreciated or classically taught in this syndrome.Blood cultures are a key investigation in the septic patient and in those that grow a Gram-negative rod, <i>Fusobacterium</i> should be considered, and suspicions of Lemierre's syndrome should be raised.
