Abstract：
BACKGROUND: Conjoined twins are a rare twin malformation commonly presenting as single amniotic sac twinning, with double amniotic sac twinning being extremely rare and poorly reported. Most conjoined twins are females.
METHODS: A woman of childbearing age conceived naturally, and at 8 wk of gestation, transvaginal ultrasonography showed an embryo and cardiac tube pulsation in both amniotic sacs. On dynamic observation, the two embryos were connected in the lower abdomen, with restricted movement. A repeat transvaginal ultrasound at 11 wk showed that the intestinal tubes of both fetuses were connected in the lower abdomen. The pregnancy was terminated and labor was induced.
CONCLUSIONS: Transvaginal ultrasound may detect conjoined twin malformations in an early stage. Our case provides diagnostic insights for ultrasonographers and can help develop early therapeutic interventions.

摘要：
背景：连体双胞胎是一种罕见的双胞胎畸形，通常表现为单个羊膜囊双胞胎，双羊膜囊孪生极为罕见，报道很少。大多数连体双胞胎是女性。
方法：育龄妇女自然受孕，在妊娠8周的时候,经阴道超声检查显示两个羊膜囊中都有胚胎和心脏管脉动。在动态观察上,这两个胚胎连接在下腹部，限制移动。在第11周进行的经阴道重复超声检查显示，两个胎儿的肠管均在下腹部连接。终止妊娠并引产。
结论：经阴道超声可早期发现连体双胎畸形。我们的案例为超声医师提供了诊断见解，并可以帮助开发早期治疗干预措施。
