Actinomycotic tubo-ovarian abscess mimicking pelvic malignancy.

A 39-year-old multipara was admitted to hospital with lower abdominal pain. She had used an intrauterine device (IUD) for 10 years. Three years ago, her tubes were ligated. Ultrasound examination revealed a 9.5 x 6 cm multiloculated cystic mass in the right part of her lower abdomen. CA-125 was also found to be increased. Since ovarian malignancy was suspected, laparotomy was performed. Pathologically, an actinomycotic tubo-ovarian abscess with sulfur granules was disclosed. Copyright 2003 S. Karger AG, Basel
