The mother of our patients was an asymptomatic 22-year-old gravida 5, para 2 woman with two previous term vaginal deliveries and two miscarriages at 12 and 13 weeks. She had a spontaneous dichorionic pregnancy with inconsistent prenatal care, marijuana use in the first trimester, and smoking throughout the entire pregnancy. Her prenatal screening showed normal serology, and she denied any history of viral infection during pregnancy. Her first prenatal ultrasound was done at 26 weeks of postmenstrual age and revealed twin A (male) to be small for gestational age with an estimated fetal weight in the 5th percentile and head circumference below the 3rd percentile. Twin B (female) was appropriate for gestational age. Repeated ultrasound at 30 weeks of gestational age showed that twin A continue to have intrauterine
AbstractBackground Cytomegalovirus (CMV) is one of the most common causes of serious viral intrauterine infections. It is universally distributed among the human population with an average incidence of 0.15 to 2%. Indeed, at least half of the women in the reproductive age have evidence of prior CMV infection. Epidemiology and Pathogenicity However, it is not a usual practice to screen asymptomatic pregnant woman or neonates for CMV. Even if a mother developed a primary CMV infection during pregnancy, up to 90% of the newborns with congenital CMV will be asymptomatic at the time of birth. Only 5 to 7% of the infected babies will be acutely symptomatic, and the typical clinical presentation includes intrauterine growth restriction, microcephaly, various cutaneous manifestations (including petechiae and purpura), hematological abnormalities (particularly resistant thrombocytopenia), hepatosplenomegaly, chorioretinitis, hepatitis, etc. In contrast, acquired CMV infection is extremely unlikely to cause any serious sequelae for the infant. Cases We present a case of congenital and acquired CMV infection in twins with a focus of dissimilarity in presentation, clinical course, and outcome.
