title: [Gliosis: follow-up and pathological study of 34 cases].
abstract: OBJECTIVE
  To discuss the etiology, clinical characteristics, pathology and canceration in gliosis.
  
  
  METHODS
  34 cases of gliosis were analyzed retrospectively follow-up for a long period. Their pathologic slices were restudied.
  
  
  RESULTS
  The causes of gliosis included cranial infection, specially infection caused by virus without distinct symptoms cerebral ischemia, brain injury, radiological treatment of brain. most cases showed symptoms of intracranial hypertension, 55.9% of the patients accompanied with epilepsy. Pathological examination revealed proliferation of small gliosis in all cases, lligodendrogliosis in 79.4% of the cases. The cases with proliferation had better rehabilitation.
