title: Ganglioglioneurocytoma of the posterior fossa.
abstract: OBJECTIVE
  Ganglioglioneurocytoma is not yet a well defined clinical and histopathological entity; recent reports outline the histopathological features of this very rare trimorphous tumor, under different names with its basic components of gangliocytoma, neurocytoma and glioma. Four previous reports described this tumor in eleven patients. This is the first case report describing ganglioglioneurocytoma in the posterior fossa.
  
  
  METHODS
  A 31-year old male with midline posterior fossa ganglioglioneurocytoma is described, providing the neuroimages and histopathological studies.
  
  
  CONCLUSIONS
  Ganglioglioneurocytoma is a rare mixed neuronal and glial tumor that can also occur in the posterior fossa.
