AbstractStuck twin syndrome usually presents with polyhydramnios in the recipient sac and severe oligohydramnios in the donor sac. The donor is displaced against the uterine wall and remains adherent in that position. We present a case in which the diagnosis was more complicated, owing to the suspension of the stuck twin by a sling within the sac of the recipient. A monochorionic diamnionic twin gestation was complicated by twin-twin transfusion syndrome at 18 weeks of gestation. In our example, the stuck twin was suspended by a sling from the placenta. The sling band represented the intertwin membrane that was folded upon itself. Amniotic fluid from the recipient twin was present in three dimensions around the stuck twin, except for the sling band. The suspension of the stuck twin by a sling within the amniotic fluid of the recipient is an unusual manifestation of the stuck twin syndrome.
