Severe large bowel obstruction secondary to infection with Actinomyces israelii.

Abdomino-pelvic actinomycosis is a rare disease, which usually follows a chronic course. However, bowel obstruction may reveal an acute clinical picture. We report on a 38-y-old female with abdomino-pelvic actinomycosis, characterized by a 10 cm long filiform stenosis of the sigmoid colon and bilateral ovarian abscesses. She developed acute ileus that required emergency surgery.
