Multiple cerebellar hemorrhagic infarctions following surgery for a huge atlantoaxial neurinoma

In the present case with multiple cerebellar hemorrhagic infarctions, venous infarction appears more likely to be the cause of cerebellar hemorrhagic infarction than arterial infarction. The most likely underlying pathomechanism is a cerebellar venous disturbance precipitated by loss of a large amount of cerebrospinal fluid, although the exact etiology remains elusive.
