A 42yo female patient suffered from bloody stool. Two years before she came to change her IUD which set up for 10 years, since then she usually got abdominal pain with bloody stool. In ultrasound examination, there is a T shape IUD into the uterus and a hyperechoic focal into the rectum. Later, CT scan confirmed 2 IUDs in the same patient, one into the uterus and others into the rectum. Endoscopic result proved that one IUD in penetrating the rectum which explained the bloody stool and her abdominal pain.
Migration of IUD may happen in women having IUD. In this case the patient had 2 IUDs because the old one could not removed and may had been excited by the new one and then perforating the wall of rectum. Ultrasound discloses difficultly intraabdominal migrating cases but easily shows the IUD into the uterus. CT scan reveals exactly the migrating IUD inside the rectum and detects another IUD inside the uterus. And in this case the findings of endoscopy is more impressive when prooves a perforated rectum by a T shape IUD type.
