title: [Idiopathic hydrocephalus in adolescence].
abstract: BACKGROUND
  Decompensation of chronic idiopathic hydrocephalus can occur at every age, but seems to be rather frequent in the middle of the second decade. From this observation, the question arises, whether or not in these cases a special manifestation of hydrocephalus occurs and, should the situation arise, whether this finding might influence the discussion about pathogenesis.
  
  
  METHODS
  We give some casuistic material about six hydrocephalic patients who became symptomatic between their 12th and 16th year of life.
  
  
  RESULTS
  All of these patients showed a tri-ventricular appearance of hydrocephalus as well as radiological signs of chronicly elevated intracranial pressure, while clinical signs and symptoms differed considerably. These findings are linked to the discussion of the pathogenesis of so-called aqueductal stenosis.
  
  
  CONCLUSIONS
  Whenever, after normal development in childhood, symptoms like increasing headache, poor concentration, dizziness or disturbances of gait appear during puberty, X-ray diagnosis of the skull is recommended. If it shows the signs of chronic elevated intracranial pressure, further investigations are necessary.
