Xanthogranulomatous tubo-ovarian abscess resulting from chronic diverticulitis

We report a case of xanthogranulomatous tubo-ovarian abscess which was preoperatively suspected to be an adnexal neoplasm. With foreign body material found in the abscess wall and vegetable fiber in the tubal lumen, a previously treated chronic diverticulitis was the presumed cause. Culture studies showed polymicrobial isolates which included Escherichia coli, an enteric pathogen. After surgery, administration of antibiotics, and revision of delayed subcutaneous wound healing, the patient is reportedly well.
