Abstract
We used magnetic resonance imaging (MRI) to evaluate nine children with neurologic disorders caused by infections with members of the herpesvirus family. MRI studies were abnormal in eight children and demonstrated a wide range of central nervous system lesions, including cystic encephalomalacia, ventricular enlargement, cerebral atrophy and focal parenchymal lesions. When compared with conventional computed tomographic scanning, MRI was more sensitive in detecting abnormalities of white matter and in defining the extent of parenchymal lesions. These studies indicate that MRI scans are highly useful in children with herpesvirus infections involving the central nervous system.
