rising from 3.8 g/dL to 12.1 g/dL). After 2 weeks, there was hydrops resolution and a reduction in MCA-PSV discordance. MR performed 3 weeks after IUT showed periventricular leukomalacia (PVL) in the DT, which died at 32 weeks with no consequences for the RT. Case 2: A MC complicated by sIUGR developed TAPS at 23 weeks with reversed-end diastolic flow in the umbilical artery of the DT (stage 3). US revealed cortical hyperecogenicity in the DT. Laser surgery was chosen with resolution of TAPS within 48 hours. At 30 weeks, MR revealed severe bilateral PVL and the couple opted for selective feticide. The RT was born at 34 weeks with a good outcome. Fetal anemia is known to increase the risk of brain injury, but it has been described only in single survivors where it follows acute hypovolemia: in such cases, it is still debatable whether a rescue transfusion can play a protective role. Here, the resolution of the anemia in the DT did not prevent the onset of brain injury: the evidence of brain edema needs to be carefully assessed before deciding the treatment option.
