title: [Intraventricular schwannoma of the choroid plexus. Case report and review of the literature].
abstract: BACKGROUND
  Intraventricular tumors account for approximately 10% of central nervous system tumors. The intraventricular schwannomas are rare because there are only 15 cases reported in the international literature.
  
  
  METHODS
  A forty-one years old female, with a history of migraines during 17 years, consulted for headaches and nausea. Brain computed tomography and magnetic resonance imaging evidenced solid nodular lesion at the right occipital horn with homogeneous contrast enhancement. Complete excision was performed through a right parietal craneotomy and a transcortical approach. The postoperative evolution was favorable. The pathology report: schwannoma. The magnetic resonance imaging 18 months after resection showed no recurrence of tumors.
  
  
  CONCLUSIONS
  Intraventricular schwannomas are very rare tumors. Surgery is treatment of choice for total resection. This is a diagnosis to consider in intraventricular tumors.
