Neuroimaging observations of three infants with congenital rubella syndrome are reported. We have observed congenital rubella syndrome lesions in the subependymal area, the basal ganglia and the deep white matter. Cranial ultrasonography defines subependymal cysts, calcification and possible vascular changes in the basal ganglia while MRI is the most sensitive to minor atrophic changes and white matter lesions. Although CT defines calcification, it is less sensitive than MRI to white matter changes and does not demonstrate subependymal cysts.
