Prenatal Course:
A 35-year-old woman, gravida 1 para 0, was referred to our Fetal Center at 32 weeks of gestation for evaluation of an enlarged fetal scrotum. On ultrasound an enlarged fetal scrotum, with a large volume of echogenic fluid, debris, and calcifications was seen (Figure 1). Testicular decent was noted (Figure 1). After careful evaluation of the fetal abdomen liver calcifications were also noted (Figure 2). There was no evidence of fetal ascites, dilated bowel loops, or meconium pseudocysts. Maternal prenatal genetic carrier screening was negative for cystic fibrosis. Testing for CMV and other infectious etiologies using maternal serology was also negative. Neonatology, pediatric surgery and pediatric urology were consulted prenatally for a suspected diagnosis of MPO. Induction of labor was scheduled at 37 weeks of gestation secondary to gestational hypertension. A 3210-gram male neonate was delivered vaginally with no complications.
