Cerebral venous thrombosis can cause obstructed venous outflow resulting in infarction or hemorrhage. Emboli can also disseminate from the venous circulation in the presence of a right-to-left shunt such as a patent foramen ovale. Emboli that originate from the heart occur due to pump failure, or due to irregular heart rhythm that disrupts smooth blood transit through the heart as in atrial fibrillation or atrial flutter. These can be due to atherosclerosis or other vasculopathies, including arterial dissections, typically of the vertebral arteries in cerebellar strokes. The thrombotic phenomenon can occur in large or small vessels, and thromboembolic can travel from large to small vessels. These can be further subdivided by the source of the obstruction in the blood vessel, either through migration from the heart or directly at the vasculature. Ischemic strokes are caused by arterial obstructions that impair blood and oxygen delivery directly. Like all strokes, cerebellar infarcts are roughly divided into ischemic and hemorrhagic events. Of all brain strokes, Cerebellar strokes account for 1% - 4%. While comprising a small fraction of strokes, cerebellar strokes are responsible for a disproportionate share of morbidity and mortality due to their sometimes subtle initial presentation and the adverse effects of reactive swelling in the posterior fossa. In the case of hemorrhagic events, bleeding can directly damage tissue and worsen these deficits. Impaired perfusion reduces oxygen delivery and causes deficits in motor and balance control.
