A cerebellar hematoma involving the vermis or larger than 3cm carries a bad prognosis, as does associated hydrocephalus. Hematomas over 2-3cm in size or those causing brainstem compression or decreased sensorium should be surgically evacuated. Smaller hematomas under 2cm or those with stable neurological status can be managed conservatively if closely monitored for signs of hydrocephalus. Guidelines associate poor outcomes with decreased consciousness, hematoma volumes over 40ml, midline shift, intraventricular hemorrhage over 20ml, age over 65, limb plegia, early hyperglycemia, or early fever.
