It is a rare complication. We present a case of acardius anephus, which was mistaken for a live anomalous singleton fetus. A 21-year-old unbooked Primigravida was seen in labour ward with a ten hours history of labour pains. Urgent transabdominal ultrasound revealed a singleton live fetus at 30 weeks gestation with gross cystic mass lesion at the level of the abdomen and polyhydramnious.?Caesarean section confirms a twin gestation with monoamniotic monochorionic single placenta. The umbilical cord of the acardiac twin was short—First twin was a live female baby, weighing 1000 g. TRAP is a rare event an early referral to feto maternal unit will improve perinatal outcome.展开更多

We present a case in which fetal demise of one fetus of a twin pregnancy had been wrongly diagnosed in the first trimester as a vanishing twin. This resulted in the unexpected occurrence of an acardiac twin in the third trimester, culminating in an acardiac twin with a birth weight higher than that of the normal twin. A review is presented on therapeutic opportunities including ligation of the umbilical cord under ultrasound or fetoscopy. This case report highlights the need for correct and early ultrasonographic diagnosis of chorionicity and detailed ultrasonographic follow-up of twin pregnancies.展开更多
