title: Possible spontaneous "birth" of a hydatid cyst into the lateral ventricle.
abstract: BACKGROUND
  Intraventricular hydatid cyst is an extremely rare entity. We report a solitary hydatid cyst in a lateral ventricle.
  
  
  METHODS
  A 7-year-old girl had a free floating intraventricular cyst, diagnosed by computerized tomography examination inside the enlarged left lateral ventricle of an associated Dandy Walker malformation. The patient underwent surgery and the cyst was removed.
  
  
  CONCLUSIONS
  To our knowledge, this is the first case report in which the natural developmental phases of an intraventricular hydatid cyst have been observed.
