A person with a cerebellar hemorrhage has bleeding within the cerebellum of the brain. An estimated 10% of intracerebral hemorrhages are believed to be cerebellar in location.

Cerebellar hemorrhage is caused by rupture of small blood vessels that supply blood to the brain cells. This interrupts the blood flow to the brain cells and causes them to malfunction, resulting in symptoms of a stroke. High blood pressure is the most common cause of rupture of the blood vessels in the brain.

Other causes of cerebellar hemorrhage include:

• Bleeding disorders:
• Hemophilia
• Low platelet count
• Aplastic anemia
• Platelet function disorder
• Cerebral arteriovenous malformation (most common cause in children)
• Cerebral aneurysm
• Head injury
• Cocaine abuse
