Foreign Bodies in the Female Reproductive Tract

Purpose:Most imaged foreign bodies of the female reproductive tract are intentionally placed, either by a medical professional or the patient herself. In many cases, these are reported as incidental findings, but occasionally studies are ordered specifically to locate wayward devices or assess for complications related to them. This requires radiologists to be able to correctly identify a wide range of foreign bodies, recognize their expected location, and assess for any associated complications. The purpose of this article is to familiarize the reader with a variety of foreign bodies and their usual positions in the female reproductive tract as well as their associated complications, if any. Methods: A search was performed of our institutional database, Montage, to find examples of frequently encountered foreign bodies of the external genitalia, vagina, cervix, uterus, and fallopian tubes in their expected positions. Further searches were made to illustrate common complications related to each. Results: Imaging of foreign bodies including external genital piercings, tampons, menstrual cups, pessaries, contraceptive rings, brachytherapy applicators, intra uterine contraceptive devices, and internal and external tubal closure devices were compiled across multiple modalities including x-ray, CT, MRI, and ultrasound. Complications including migration, perforation, and infection were reviewed. Conclusion: Foreign bodies of the female reproductive tract are ubiquitous and should be readily recognized by radiologists. Comprehensive evaluation includes assessment for correct location and device-related complications.
