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.
左炔诺孕酮宫内节育器（LNG-IUD）是一种含有激素的装置，已获许可用于治疗月经过多和避孕。尽管有报道称，与其他非激素宫内节育器类似，该装置也会出现诸如穿孔等并发症，但由于LNG-IUD与铜制宫内节育器相比，在超声检查中有不同的表现，因此使用该装置诊断此类并发症较为困难，这些病例报告旨在强调这一点。
