The findings on magnetic resonance imaging (MRI) or computed tomographic scan in 35 children with acute encephalopathy (AE) induced by infections were categorized into five groups: (1) normal findings (11 cases), (2) normal findings in the acute phase followed by mild brain atrophy (1 case), (3) severe brain edema which developed within 48 hours after the onset of AE (7 cases), (4) diffuse cortical necrosis which appeared around 4 days after the onset of AE (9 cases), and (5) symmetric thalamic lesions (7 cases). Their outcomes were as follows: three cases developed epilepsy in (1) and (2); six died and one had a sequel of severe brain damage (SBD) in (3); all cases survived but had SBD in (4), and four died, one had SBD, and 2 recovered in (5). Serum AST were elevated in 7.7 and 6 cases in (3), (4) and (5), respectively. In all of them, there were more than one case having liver histologies consistent with Reye syndrome.

We studied the clinical and CT findings of 3 children with acute encephalopathy associated with adenovirus type 7 (AD-7) infection. Seizures in all the patients developed from 8 to 10 days after the onset of pyrexia. The values of serum AST, LDH and CRP elevated and those of WBC and serum protein decreased at the onset of encephalopathy. None of the patients had CSF leukocytosis. CT showed mild brain atrophy in all patients. A steroid pulse therapy was effective in one patient. The pathogenesis of encephalopathy is unknown. However, its onset and the success of the steroid pulse therapy suggested that it is a post infectious encephalitis. These findings, as well as the data of blood examination and of previous reports, implicated adverse effects of cytokines in the pathogenesis of this encephalopathy.

CT/MRI findings, laboratory examinations and prognoses of 42 patients with acute encephalopathy (AE) (Japan Coma Scale > or = 200) were reported. 1. Findings on CT/MRI were divided into the following 7 categories: Group 1 (normal), Group 2 (CT/MRI looked normal in acute phase, but brain atrophy developed and progressed slowly by weeks or months), Group 3 (CT/MRI looked normal within a few days after the onset of AE, but cortical laminar necrosis developed at 4-5 days after the onset), Group 4 (marked brain edema developed within 2 days after the onset of AE), Group 5 (AE with symmetric thalamic lesions), Group 6 (symmetric pallidum, lesions on MRI which appeared after brain edema disappeared), and Group 7 (the brain shrinked during acute phase, which normalized on the follow up CT/MRI). 2. Serum AST elevated in approximately 50% of the patients with AE. Sixty percent of them exhibited DIC, whose prognoses were poor. Cerebrospinal fluids (CSF) neopterin (NP) and/or interleukin (IL)-6 were elevated in all the 8 patients examined. In the two cases whose serum NP and IL-6 were measured at the same time, their values in the CSF were higher than those in the serum in one case, and almost the same in the other. In a patient with a condition mimicking hemorrhagic shock and encephalopathy, serum IL-6 concentration was very high (94,000 pg/ml). 3. Mild hypothermia (around 34 degrees C) combined with methylprednisolone pulse therapy was excellently effective on AE. A 6-year-old boy exhibited tonsillar herniation at admission recovered well to be able to run. 4. Differentiation between Reye syndrome and HSE, and the pathogenesis of AE were also discussed.
