A vanishing twin also known as fetal resorption is a fetus in a multi-gestation pregnancy which dies in utero and is then partially or completely reabsorbed by the twin.The occurrence of this phenomenon is sometimes referred to as twin embolisation syndrome or vanishing twin syndrome (VTS) since the 1980s when twin pregnancies were made visible early on by means of ultrasound.Occasionally rather than being completely reabsorbed the dead fetus will be compressed by its growing twin to a flattened parchment-like state known as fetus papyraceus.If the fetus is absorbed completely there are usually no further complications to the pregnancy other than first trimester vaginal bleeding.
