title: Extensive white matter involvement in hemorrhagic shock and encephalopathy syndrome.
abstract: Reported is a case of hemorrhagic shock and encephalopathy syndrome (HSE) with extensive white matter involvement. A three year old, previously healthy boy was presented with an acute onset of fever, loss of consciousness and convulsions. He had disseminated intravascular coagulation, metabolic acidosis, non-ketotic hypoglycemia and hepatorenal dysfunction. The computed tomography (CT) scan of his head on the second day of illness demonstrated symmetric, extensive low-density areas in the cerebral and cerebellar white matter. The child died on the 13th hospital day. A post-mortem histopathological examination of the liver revealed centrilobular necrosis and infiltration of fatty acid droplets. The concentrations of serum 2',5'-oligoadenylate synthetase and urinary neopterin were markedly elevated, indicating excessively activated cell-mediated immunity. This overproduction of inflammatory cytokines might play an important role in the pathogenesis of the brain lesion as well as in other clinical and laboratory manifestations. The patient had a decreased serum level of alpha l-antitrypsin, which may have been associated with the development of uncontrolled inflammation and coagulation disorder.
