Missing IUD and utilization of fluoroscopy for management: A case report

摘要

Introduction: A missing intrauterine device (IUD) poses challenges in diagnosis and treatment. Extrauterine placement of IUDs may cause difficulty in localization. We report a case where use of fluoroscopy just prior to laparoscopic intervention to remove the missing IUD was beneficial. Case: This case report involves a 35-year-old woman who was diagnosed with a missing thread 2 years after insertion of a levonorgestrel IUD (Mirena). Initial diagnostic workup consisting of abdominal X-ray, an ultrasound and diagnostic laparoscopy failed to localize the IUD. We performed an office pelvic ultrasound which confirmed that an IUD was present but could not specifically localize the IUD in the pelvic or abdominal cavity. Hence, we utilized fluoroscopy just prior to laparoscopy to localize and remove the missing device and allow its removal. Conclusion: Various imaging modalities aid in detecting a missing IUD, but proper selection of fluoroscopy helped to localize extrauterine placement of an IUD device. We suggest that utilization of this imaging method just prior to laparoscopy may be of value in selected cases.
