Observations in five cases of spontaneous cerebellar hemorrhage

Five cases of spontaneous intracerebellar hemorrhage are reported. Three had a vascular malformation and two had mild hypertension. The presenting symptom was sudden headache followed by nausea and vomiting. Signs of brain stem dysfunction without prominent cerebellar deficit were the commonest feature. Meningeal involvement was present in the majority of cases. Unsuspected sudden death can occur. It is suggested that patients below the age of 30 who present with sudden headache followed by brain stem dysfunction with or without a subarachnoid hemorrhage, and patients over the age of 45 who present this picture along with subarachnoid hemorrhage should be investigated urgently with contrast studies for possible cerebellar hemorrhage.
