title: Pineal germinoma with intratumoral hemorrhage after neuroendoscopic tumor biopsy.
abstract: METHODS
  We report an intratumoral hemorrhage immediately after a ventricular endoscopic procedure in an 18-year-old man who had a pineal germinoma with symptomatic hydrocephalus. The patient was successfully treated using long tract external ventricular drainage and urgent radiation therapy.
  
  
  CONCLUSIONS
  The contributing factors for the acute reduction of intracranial pressure to zero during the endoscopic procedure are discussed.
