The aim of the investigation was to determine the patterns of cerebral involvement on computed tomography (CT) and magnetic resonance (MR) imaging in @entity6079 . Four @entity1 between the ages of 2 and 11 years presented over a 5-year period with a diagnosis of @entity6079 . Their imaging studies and clinical data were reviewed retrospectively. The medical histories of all four @entity1 were noncontributory except for recent bouts of chickenpox 1 week to 3 months prior to hospitalization. Three @entity1 presented with @entity191 manifestations. Bilateral, symmetric hypodense, nonenhancing @entity21 were found on CT. These areas showed nonenhancing low signal intensity on T1-weighted images and high signal intensity on T2-weighted images on MR. One @entity1 presented with diffuse, multiple gray and @entity62 of similar imaging characteristics; some lesions, however, did enhance. This @entity1 had no gait disturbances. @entity6079 can produce two patterns of dramatic CT and MR findings. With an appropriate history and clinical findings, varicella as a cause of bilateral basal ganglia or diffuse @entity75 can be differentiated from other possible etiologies which include @entity130 , @entity519 , @entity209 and @entity17 .
