The Levonorgestrel intrauterine device (LNG-IUD) is a
hormone-containing device licensed for treatment of menorrhagia
and contraception. Though complications such as perforation
have been reported similar to other non-hormonal intrauterine
devices, the diagnosis of such complications is difficult with
this device because the LNG-IUD has a different ultrasound
appearance compared to copper devices and these case reports
are intended to emphasize this point.
