Early sonographic diagnosis of intrauterine device migration to the adnexa.

Uterine perforation is an uncommon complication of intrauterine devices (IUDs). Perforating IUDs can migrate to various locations but paradoxically are rarely found in ovaries or broad ligament. We describe an unusual case of a 23-year-old woman 1-month postpartum with an IUD translocation to the right adnexa. The IUD was inserted only 1 week prior to presentation, and she experienced pain on insertion. After visualization by ultrasound, the IUD was laparoscopically removed. We suggest early use of ultrasound in cases of potential IUD migration, particularly in high-risk patients and when IUD insertion causes pain. (c) 2009 Wiley Periodicals, Inc.
