Central nervous system infection due toClostridium septicum: A case report and review of the literature

A patient with end stage breast cancer was admitted to hospital due to fever, chills, multiply eroded discharging wounds, and sudden onset of left hemiparesis.Clostridium septicum bacteremia and brain abscess were diagnosed. The patient was treated successfully with intravenous penicillin and clindamycin and stereotactic aspiration of the abscess. Eleven cases ofC. septicum central nervous system infection are reviewed. They showed an extremely fulminant course and high fatality. Nevertheless, some relationship seems to exist between outcome and type of brain lesion. Hemolytic-uremic syndrome associated with central nervous system infection is also discussed, because all these cases in the literature were due to this organism. Early diagnosis and aggressive treatment, including surgical drainage and appropriate antibiotics, are the key to improving the prognosis. A long-term prophylactic oral antimicrobial agent is suggested for patients who survive this infection.
