Background

We present a rare case of pregnancy and invasive placentation in a unruptured, noncommunicating rudimentary uterine horn at 20 weeks’ gestation.

Case

The patient was followed with ultrasound throughout early pregnancy and initial imaging for dating purposes showed a pregnancy within a communicating right horn of the uterus. At the 18-week anatomy ultrasound, the pregnancy was discovered to be within the noncommunicating, rudimentary left horn of the uterus. This was confirmed using pelvic magnetic resonance imaging. The patient opted for surgical management and subsequently underwent laparotomy and removal of the noncommunicating uterine horn and pregnancy. Placental tissue was adherent to the level of the serosa during surgery and pathologic diagnosis was significant for a placenta increta.

Summary and Conclusion

The patient recovered well from surgery and subsequently went on to have a successful term pregnancy delivered via cesarean section for breech in the right horn 15 months later.

非连通子宫角中的妊娠和胎盘植入

背景

我们介绍了一个罕见的妊娠 20 周时未破裂、不相通的未发育子宫角发生侵入性胎盘的病例。

案件

患者在整个妊娠早期接受超声检查，用于约会目的的初始成像显示在子宫的连通右角内怀孕。在第 18 周的解剖超声检查中，发现妊娠位于不连通的、发育不全的子宫左角内。使用骨盆磁共振成像证实了这一点。患者选择了手术治疗，随后进行了剖腹手术并切除了不相通的子宫角并妊娠。胎盘组织在手术过程中粘附于浆膜水平，病理诊断对胎盘植入具有重要意义。

总结与结论

患者从手术中恢复良好，随后在 15 个月后通过剖宫产成功进行了右角臀位足月妊娠。
