Infección congénita por citomegalovirus con una afección ecográfica progresiva y grave

Cytomegalovirus is the most frequent congenital infection with an incidence of approximately 1% and a high rate of fetal involvement and sequelae. In the absence of universal screening, diagnosis of this infection is usually based on abnormal findings during routine ultrasound scan. We present a case showing progressive abnormalities on ultrasound. Initial abnormal findings consisted of hyperechogenic bowel and oligohydramnios at 17 weeks and subsequent abnormalities consisted of marked ventriculomegaly, hepatomegaly and ascites at 21 weeks when cytomegalovirus was detected in the amniotic fluid by polymerase chain reaction.
