====== Spontaneous cerebellar hemorrhage etiology ======

Etiologies are similar to ICH of any location; however, some nuances:

1. [[Hypertension]] is a factor in up to two-thirds of [[cerebellar hemorrhage]]s

2. [[Cerebellar Arteriovenous Malformation]] is a consideration, an [[aneurysm]] is very rare (possibly [[AICA aneurysm]], but usually only in association with other high-flow lesions, e.g. AVM)

3. may be related to recent previous spinal or supratentorial surgery
----
Hypertensive [[cerebellar hemorrhage]] may be the first presentation of underlying tumor, specifically [[cerebellar glioblastoma multiforme]]. Patients undergoing surgery for cerebellar hemorrhage should have clot specimens sent for histologic examination and have pre- and postcontrast MRIs. Patients not undergoing surgery should have MRIs done after hematoma resolution to rule out underlying tumor
