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.

CASE SUMMARY

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.

CONCLUSION

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.

Keywords: Double amniotic sac, Conjoined twins, Yolk sac, Transvaginal ultrasound, Case report

Core Tip: We recently diagnosed a case of bi-amniotic sac conjoined twin fetuses at 8 wk of gestation, reports of such cases are rare nationally and globally. We provide insights into the early diagnosis and treatment of conjoined twin fetuses for colleagues.
