Acardiac twinning with sacrococcygeal teratoma–A rare case report and review of literature

Acardiac twin is a rare complication of monozygotic twin pregnancies. It accounts for 1% of monochorionic twin gestations with an incidence of 1 in 35,000 births. We report a rare case of acardiac twin with sacrococcygeal teratoma in a monochorionic twin gestation in view of rare incidence and diagnostic challenge.
