[Acute encephalopathy associated with centrilobular necrosis of liver mimicking Reye's syndrome--report of two cases].
Recent experience suggests that a diagnosis of Reye's syndrome based on clinical and biochemical grounds alone may be unreliable. Two patients are presented here, whose clinical manifestation suggested Reye's syndrome. The biochemistry data were also compatible with Reye's syndrome except that the levels of serum AST and ALT were significantly higher with normal serum ammonia level. Blood amino acid and urinary organic acid assay all showed negative findings. Histological findings of the liver showed marked centrilobular necrosis rather than fatty metamorphosis. The muscle biopsies did not show lipid accumulation in the muscle fibers as well. The findings in our patients suggested that a confirmatory diagnosis of Reye's syndrome requires a characteristic pathological findings of the liver in order to differentiate Reye's syndrome from Reye-like syndrome, especially acute encephalopathy associated with centrilobular necrosis of the liver.
