Post-partum, post-sterilization tubo-ovarian abscess caused by Fusobacterium necrophorum: A case report

Abstract

Introduction. Post-partum, post-sterilization tubo-ovarian abscess is a rare event. Fusobacterium necrophorum subspecies funduliforme, a normal flora found mainly in the oral cavity, appears to be the etiologic organism. Case presentation. In this case report, a 25-year-old Thai woman had a post-partum, post-sterilization tubo-ovarian abscess caused by the strictly anaerobic bacterium, Fusobacterium necrophorum subspecies funduliforme. Progressively severe symptoms started 3 weeks after her third vaginal delivery with a tubal sterilization on the following day. On admission, she presented with peritonitis and impending shock. An exploratory laparotomy showed a ruptured left tubo-ovarian abscess. A segment of her ileum had to be resected because of severe inflammation. Conclusions: Fusobacterium necrophorum subspecies funduliforme can be an etiologic organism of a ruptured tubo-ovarian abscess following tubal sterilization in a healthy host. © 2012 Chayachinda et al.; licensee BioMed Central Ltd.
