The case of a 5-month-old boy with sudden onset of shock, encephalopathy, watery diarrhea, bleeding tendency, and impaired hepatic and renal functions was reported. The different pathological findings as compared with the previous reports made the term "hemorrhagic shock encephalopathy-like syndrome" (HSE-like syndrome) more suitable for this case. Marked fatty metamorphosis with hemorrhage was found with a light microscope. Electron microscopy revealed flocculent densities in the mitochondria which might be a poor prognostic indicator in this syndrome. Diffuse electron-dense deposits in the peroxisomes were also seen and the significance of this finding was discussed. The patient died on the third day after admission due to multiorgan failures in spite of our aggressive management.

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.
