title: [The clinicopathological study of infantile cytomegalovirus hepatitis].
abstract: OBJECTIVE
  To investigate the clinicopathological features of infantile cytomegalovirus hepatitis.
  
  
  METHODS
  Liver biopsies from 30 cases of infantile cytomegalovirus hepatitis were observed under optical microscope and electronic microscope.
  
  
  RESULTS
  The main clinical manifestations were jaundice, splenohepatomegaly and hypohepatia. Laboratory test showed dysfunction of liver, high level of CMV DNA, and high titer of anti-CMV antibody. Imaging examination demonstrated hepatomegaly. The histological changes were hepatocellular degeneration, necrosis, apoptosis, and fibrosis. The histological characteristics of cytomegalovirus hepatitis, including intranuclear inclusions in multinucleated giant cells and pseudo-lumens, were also observed under optical microscope. In addition, virion was observed in the nuclei and cytoplasm of hepatocytes under electronic microscope.
  
  
  CONCLUSIONS
  The viral DNA and serological tests have limited utility for the diagnosis of infantile cytomegalovirus hepatitis, and the final diagnosis depends on histopathology.
