Fusobacterium necrophorum is a well-known cause of Lemierre's syndrome. Recent studies suggest a causative association between F. necrophorum and acute appendicitis. We present a case of a 15-year-old previously healthy girl who presented with acute non-perforated appendicitis, intra-abdominal abscesses and thrombosis that led to omental necrosis. This resulted in a life-threatening septic shock with the need for prolonged intensive care. We suggest that F. necrophorum identified in pus from the abdomen caused this fulminant variation of appendicitis with findings similar to those seen with Lemierre's syndrome.

Fusobacterium nucleatum is an anaerobic oral commensal and a periodontal pathogen associated with a wide spectrum of human diseases. This article reviews its implication in adverse pregnancy outcomes (chorioamnionitis, preterm birth, stillbirth, neonatal sepsis, preeclampsia), GI disorders (colorectal cancer, inflammatory bowel disease, appendicitis), cardiovascular disease, rheumatoid arthritis, respiratory tract infections, Lemierre's syndrome and Alzheimer's disease. The virulence mechanisms involved in the diseases are discussed, with emphasis on its colonization, systemic dissemination, and induction of host inflammatory and tumorigenic responses. The FadA adhesin/invasin conserved in F. nucleatum is a key virulence factor and a potential diagnostic marker for F. nucleatum-associated diseases.

Fusobacterium necrophorum is a non-spore-forming, obligate anaerobic, filamentous, gramnegative bacillus that frequently colonizes the human oral cavity, respiratory tract, and gastrointestinal tract. Fusobacterium species have rarely been implicated in cases of gastrointestinal variant of Lemierre's syndrome. We describe a case of F. necrophorum bacteremia associated with suppurative porto-mesenteric vein thrombosis (PVT) following acute ruptured appendicitis. In addition, we list the documented twelve cases of Fusobacterium pylephlebitis. Recanalization of the porto-mesenteric veins and relief of the extrahepatic portal hypertension were achieved with early empiric antibiotic and local thrombolytic therapy. Our patient's case underscores the importance of recognizing Fusobacterium bacteremia as a possible cause of suppurative PVT after disruption of the gastrointestinal mucosa following an acute intraabdominal infectious process. Early treatment of this condition using anticoagulation and endovascular thrombolysis as adjunctive therapies may prevent PVT complications.
