Pregnancies were followed with fetal brain neurosonogram every 2\u00a0weeks and fetal brain MRI (magnetic resonance imaging) was performed when indicated at 28\u201332\u00a0weeks of gestation; post\u2010natal brain imaging included neonatal brain ultrasound. Pregnancies with pre\u2010 and post\u2010natal brain lesions were compared to those without such findings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 23 monochorionic diamniotic pregnancies were diagnosed with TAPS over the study period resulting in perinatal survival of 91.3% (42\/46). In 6\/23 (26%) pregnancies and 7\/46 (15.2%) fetuses pre\u2010 or post\u2010natal brain lesions were detected, of whom five were the polycythemic twins and two were the anemic twins. Brain findings included intra\u2010cerebral hemorrhage and ischemic lesions and were diagnosed prenatally in 6\/7 (85.7%) cases.
