title: [Computed tomography and magnetic resonance imaging of the brain in congenital rubella syndrome].
abstract: Nine children with congenital rubella syndrome were examined with respect to the relation between clinical symptoms and the findings of computed tomography (CT, 9/9 cases) and magnetic resonance imaging (MRI, 7/9 cases). All patients had deafness, and three had relatively severe sequelae in the central nervous system (CNS), such as mental retardation (MR), cerebral palsy (CP) or microcephaly. In four patients, dilatation of the lateral ventricles was found by CT; in four patients, low-density areas were noted in the periventricular white matter and/or the subcortical white matter; one patient showed a spotty calcified area in the lenticula. No abnormal findings were found by CT in other three patients. MRI in seven children demonstrated areas of prolonged T1 and T2 relaxation times in the white matter in all of them. In relation to clinical symptoms, five patients without dilatation of the lateral ventricles had no sequelae except deafness. On the other hand, in four patients with dilation of the lateral ventricles, three had MR, CP or microcephaly. This study showed that there was a close relation between the ventricular dilatation and sequelae with in CNS, whereas abnormal intensity areas in the white matter found by MRI were not related well to the sequelae of CNS.
