title: Hydrocephalus and macrocrania: surgical or non-surgical treatment of postshunting subdural hematoma?
abstract: BACKGROUND
  Subdural hematoma is a well-known complication of hydrocephalus shunting procedures. Since the advent of modern neuroimaging techniques, a more realistic incidence of subdural hematomas in shunted patients has been recognized. The description of several asymptomatic cases raises the problem of choosing the most appropriate therapeutic policy for such a condition.
  
  
  METHODS
  We report two cases with long standing hydrocephalus and macrocrania in which bilateral huge acute and subacute postshunting subdural hematoma developed and remained asymptomatic.
  
  
  RESULTS
  The first patient was treated initially by surgery. Subsequently, despite the persistence of the subdural collections, a nonsurgical policy was chosen. The second patient was deliberately nonsurgically treated.
  
  
  CONCLUSIONS
  On the basis of our experience, we conclude that a nonsurgical policy should be followed in patients with long standing hydrocephalus and macrocrania, if they develop postshunting large hemorrhagic subdural collections and remain asymptomatic.
