Missing intrauterine device migrated to terminal ileum resembling adnexal mass: A case report.

INTRODUCTION AND IMPORTANCE: Although IUD has become more popular in recent years, its migration through uterine perforation is a rare but serious complication. PRESENTATION OF CASE: We present the case of a young otherwise healthy woman with a missing IUD that had penetrated terminal ileum. CLINICAL DISCUSSION: The incidence of uterine perforation after IUD insertion has been reported 1.3 to 1.6 per 1000 insertions. Although a rare complication, it can cause serious problems requiring major surgery. CONCLUSION: Uterine perforation and migration of IUD is a rare but serious complication that should be considered in all missing IUD threads.
