Objective.  To determine whether newborn cranial computed tomographic (CT) scan abnormalities predict an adverse neurodevelopmental outcome in children with symptomatic congenital cytomegalovirus (CMV) infection and to examine the association between clinical findings at birth and imaging abnormalities.

Methods.  The data from 56 children with symptomatic congenital CMV infection who underwent cranial CT scans as newborns and were enrolled in a long-term follow-up study were analyzed. The incidence of sequelae was compared between the groups of children with normal and abnormal imaging studies. The relationship between CT scan results and other newborn findings was also examined.

Results.  Abnormal CT scans were noted in 70% of subjects; intracerebral calcification was the most frequent finding. Most of the children with an abnormal newborn CT scan (90%) developed at least one sequela, compared with 29% of those with a normal study. Only 1 child with a normal CT scan had an IQ <70, in contrast to 59% of those with imaging abnormalities. In addition, almost half of the children with CT abnormalities had an IQ <50 compared with none of those with a normal CT scan. Newborn CT abnormalities were also associated with an abnormal hearing screen at birth and hearing loss on follow-up. None of the neonatal neurologic findings were predictive of an abnormal CT scan.

Conclusion.  In neonates with symptomatic congenital CMV infection, a cranial CT scan is a good predictor of an adverse neurodevelopmental outcome. In addition, newborn clinical and laboratory findings did not predict neuroradiographic abnormalities in neonates with symptomatic congenital CMV infection.
