Fusobacterium species are well described as the causative pathogen in Lemierre's 
syndrome, a suppurative thrombophlebitis of the jugular vein. However, they are 
less recognized for a unique variant of Lemierre's syndrome presenting with 
invasive intraabdominal infection and associated portal vein thrombosis. We 
describe a case of Fusobacterium nucleatum with hepatic abscess and septic 
pylephlebitis.
