Three patients with encephalopathy clinically indistinguishable from Reye syndrome but associated with elevated cold-agglutinin titers and antiglobulin-I autoimmune hemolytic anemia are reported. The patients were treated with exchange transfusions, dexamethasone, controlled hyperventilation, and intracranial pressure monitoring. Liver biopsy specimens in two of the three patients showed fatty infiltration of the hepatocytes, but the light microscopic and electron microscopic appearance of the liver was not typical for Reye syndrome. These patients are reported to alert physicians to a metabolic encephalopathy in children which mimics Reye syndrome, but is distinctly different in clinical course and complicated by cold agglutinins and an autoimmune hemolytic anemia.
