Fusobacterium nucleatum: More Than Just an Oral Anaerobe

Fusobacterium nucleatum is a strict anaerobe that is indigenous to the human oral cavity, where it coexists with more than 500 other species. It is associated with paranasal sinus, odontogenic, and pulmonary infections. In literature, cases of Fusobacterium nucleatum are rare. Here we report a case of a patient with multiple brain abscesses caused by Fusobacterium nucleatum. This case report looks to assist clinicians in determining the true etiology of this organism, which can change patient management based on the current literature review and similar case studies.
