Severe narrowing of left cavernous carotid artery associated with Fusobacterium necrophorum infection.

Severe oropharyngeal infection can result in Lemierre's disease, a syndrome with high mortality secondary to inflammation and thrombosis of cervical and intracranial veins with involvement of contiguous structures; however arterial involvement is rare. We report a case of Lemierre's disease in a 12 year old boy with severe narrowing of the left cavernous carotid artery.
