Twin reversed arterial perfusion syndrome is a rare condition seen in monochorionic twin gestation. The incidence is 1 in 35000 births and 1 in 100 monozygotic twin pregnancies. It is a complication of twin pregnancy that occurs due to preferential blood flow within the vascular communication between the two fetuses. We hereby report a case of 24-year-old primigravida referred in view of twin pregnancy with demise of one twin. On serial ultrasound it was misinterpreted as missed abortion of one twin and twin papyruses in further scans. But the consistent growth of the demised fetus made us think of acardiac twin as a differential diagnosis. When she presented in labour to our hospital, she delivered an acardiac anceps fetus along with a normal fetus. Keywords: Acardiac twin, Twin reversed arterial perfusion, Monozygotic twins.
