Abstract
A 45-year-old male presented with sudden onset of severe headache, mild disorientation, and gait disturbance due to intracystic hemorrhage from a cerebellar hemangioblastoma. He was successfully treated with ventricular drainage followed by total removal of the tumor. Reported cases of intracranial hemangioblastoma with massive hemorrhage show male predominance, tend to be solid rather than cystic, and occur in supratentorial more than infratentorial locations. Thin-walled and dilated vessels in the present and other cases were a possible cause of hemorrhage. Massive hemorrhage from hemangioblastoma is rare but needs prompt treatment because of the relatively high mortality.
