On routine prenatal ultrasound at 18 weeks' gestation, a 30-year-old, gravida 2, para 0, Hispanic woman was noted to have a fetus with abnormally large, echogenic lungs and fetal ascites. Her pregnancy previously had been unremarkable except for diet-controlled gestational diabetes. She was referred to our tertiary care center. Fetal magnetic resonance imaging (MRI) was performed at 23 weeks' gestation with fast imaging techniques, including spin-echo and gradient-recalled images in axial, sagittal, and coronal planes.
