Ovarian abscess associated with incomplete abortion and intrauterine contraceptive device.

A 28-yera-old woman with an intrauterine device (IUD) was admitted to hospital with signs of incomplete abortion. The IUD was removed and curettage revealed necrotic infected decidua with no trophoblastic cells or chorionic villi. The patient subsequently developed multiple abscesses in the right ovary. The mechanism of development of ovarian abscesses in patients with IUD or with infected incomplete abortion is discussed.
