Abdominal and pelvic actinomyces has been called "one of the greatest imitators in clinical practice". Actinomycosis is a crhonic suppurative infection due to a gram positive, non-spore-forming, anaerobic bacteria. The organisms are indigenous in the oral cavity, GI tract, and genital tracts, with opportunistic infection occurring when the mucosal barrier is broken, leading to multiple abscess formation, fistula or mass lesion. Actinomyces has three major forms of clinical manifestation: cervicofacial, thoracic and abdominal. We present a case of abdominal-pelvic actinomycosis.
