The twin reversed arterial perfusion (TRAP) sequence is an anomaly unique to monochorionic multiple pregnancies. 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.
