[A case of cerebellar glioblastoma with massive cerebellar hemorrhage].

A case is reported of glioblastoma multiforme (GM) of the cerebellum associated with an intracerebellar hemorrhage. A 54-year-old male was admitted to our hospital with sudden onset of headache and nausea. CT scan showed right intracerebellar hemorrhage. The patient received conservative therapy and was discharged without any neurological deficits. However a second cerebellar hemorrhage attacked him ten days after discharge. His level of consciousness deteriorating, he underwent suboccipital craniectomy and the hematoma with the surrounding elastic tissues was excised. There were no findings suggesting hemorrhage within the tumor on the preoperative neuroimagings, but histological examination confirmed GM with massive hemorrhage. To our knowledge, only 2 cases of cerebellar GM with massive hemorrhage have been reported in the literature. Our case indicates cerebellar GM should be taken into account as a possible cause of cerebellar hemorrhage.
