Fetus papyraceous is a relatively rare complication in twin pregnancy. The occurrence of fetus papyraceous is frequently associated with perinatal morbidity in the other twin, making antenatal diagnosis of this condition desirable. Ultrasound detection is not always possible due to anatomical position and technical difficulties. A case of fetus papyraceous, found during Caesarean section for obstructed labour is reported and the implications of antenatal detection are discussed.
