title: Pelvic Actinomyces israelii abscess: a differential diagnosis of a pelvic mass.
abstract: A 52-year-old woman was admitted to our district general hospital, with a rapidly growing, increasingly tender mass in the right iliac fossa, difficulty mobilising with a fixed flexion deformity of the right hip and 15 kg weight loss in 5 months. Her 8-month long surgical history for investigation of a pelvic mass stemmed from the removal of an intrauterine device. It included radiological and surgical investigations. We report the second case in the literature, of a patient presenting with abdominal wall abscess, psoas abscess and hydronephrosis as a long-term complication of Actinomyces israelii infection of the ipsilateral ovary with a favourable outcome having excluded ovarian malignancy.
