Incidental detection of a transmigrated intrauterine device

Abstract

The intrauterine device (IUD) is among the most effective forms of birth control available, with important advantages over other methods of contraception. The most striking adverse event associated with IUD use is uterine perforation and migration of the device. Contrary to what one might assume, perforation is often silent and the wayward device is either detected after further sequellae or found incidentally by imaging. The radiologist should be aware of the natural course, presentations, diagnostic evaluation and treatment (if any) for this misplaced foreign body.
