[Hemorrhagic shock syndrome with encephalopathy].

The occurrence in a previously healthy infant of sudden febrile encephalopathy with shock and metabolic acidosis associated with liver and renal failure and bloody watery diarrhea has been reported by several authors in recent years. We report the same association in a 3 1/2 month-old infant. We discuss the similarities between this clinical picture and malignant hyperthermia and Reye syndrome.
