Imagerie des thromboses veineuses septiques viscérales à germes anaérobies

Venous thrombosis has been reported at various locations during Fusobacterium species (sp.) and Bacteroides sp. septicemia. The original description, by André Lemierre, was of Fusobacterium necrophorum septicemia secondary to oropharyngitis, associated with internal jugular vein thrombosis and pulmonary abscess. Septic pylephlebitis results from a similar pathophysiological process: mesenteric-portal vein extension from a gastrointestinal infection site. Genital veins may also be involved. Imaging, and CT in particular, makes an essential contribution to the diagnosis and assessment of the infectious extension.
