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.
