ABSTRACT
Congenital cytomegalovirus (CMV) infection is the most common nongenetic cause of sensorineural hearing loss and a major cause of visual, intellectual, and neurodevelopmental impairment worldwide. The seroprevalence of CMV among women of childbearing age in developing countries reaches almost 100%, and the incidence of CMV infection in neonates is 1%–2%. Approximately 87% of the infected neonates are asymptomatic at birth and 13% of them have permanent sequelae. The burden of congenital malformations due to congenital CMV infection is higher than that due to Down syndrome, fetal alcohol syndrome, and spina bifida. Nevertheless, there is little knowledge regarding congenital CMV pathogenesis, diagnosis, treatment, and prevention. In this study, we report a case that showed sequential changes of fetal brain following CMV infection in pregnancy. Additionally, we reviewed the latest information on the diagnosis, treatment, and prevention of congenital CMV infection.
