Uterine perforation is a serious problem which can happen after intrauterine device (IUD) insertion. Migration of the IUD to the pelvic and abdominal cavity or adjacent organs may be seen following perforation of the uterus. Migration of an IUD to a far intra-abdominal site is extremely rare. The patient reported here had undergone an IUD placement 30 years previously and had no problems during this period. The IUD was incidentally found at the left upper quadrant of the abdomen in the mesentery.
