Sporadic Fusobacterium Bacteremia as an Atypical Cause of Acute Hepatitis in a Young Caucasian Woman

Fusobacterium species are gram-negative anaerobic non-spore-forming bacteria, which colonize mucous membranes in humans. Over the recent decade, the significance of these organisms has been increasingly recognized. We describe a rare case of acute hepatitis, which was found to be likely due to Fusobacterium nucleatum, grown on blood culture. In our case, the hepatitis caused by this microorganism resolved completely without any long-term sequelae to the liver, through conservative management namely intravenous antibiotics and supportive therapy only. This case highlights that early detection and prompt treatment in a case of acute hepatitis resulted in a good outcome. In addition, this case also illustrates that the differential diagnosis can be varied in cases of acute hepatitis.
