title: Neuro-ophthalmic manifestations of hemangiopericytoma.
abstract: OBJECTIVE
  To describe the neuro-ophthalmic presentations of a rare intracranial tumor, hemangiopericytoma.
  
  
  METHODS
  Retrospective multicenter case series.
  
  
  RESULTS
  The neuro-ophthalmic and radiographic features of hemangiopericytoma are reviewed. The clinical presentation may mimic meningioma and the pre-operative distinction between meningioma and hemangiopericytoma is important because the evaluation, management, treatment, and prognosis differ significantly for the two lesions.
  
  
  CONCLUSIONS
  We report five cases of intracranial hemangiopericytoma and review the neuro-ophthalmic findings of this uncommon entity.
