Case Report


An oral infection harboring Fusobacterium species can gain entrance to the liver via hematogenous spread in the form of septic embolus, and can thereby cause abscesses. Such spread, described as Lemierre syndrome, is life threatening. We present such a case history of a man in his mid-40s, who presented with infection and Fusobacterium liver abscess with an acute fulminant disease course. The initial diagnosis was arrived at by ultrasound imaging and blood investigations. He was treated with antibiotics, ultrasound-guided liver abscess drainage, and extraction of the infected molar tooth. He was discharged 6 weeks after admission. To date, there have been no reports describing the ultrasound images of a Fusobacterium liver abscess in detail. Hence, we herein present the ultrasound images of a Fusobacterium liver abscess.
