Abstract

A clinical study was done on 16 cases of cerebellar hemorrhage and 3 cases of cerebellar infarction which were diagnosed with brain CT scan at Keimyung university Dongsan hospital from July 1981 to June 1985 and conclusions obtained are as follows. 1. The incidence of cerebellar hemorrhage and infarction was 3.5% and 0.6% of all spontaneous intracranial parenchymal hemorrhage and infarction, respectively. 2. The most prevalent age group was 7th decade and sex ratio was higher in male in cerebellar stroke. 3. Major single percipitating factor of cerebellar stroke was hypertension. 4. Most of cerebellar stroke showed catastrophic or sudden onset type. 5. The most common initial symptoms of cerebellar stroke were nausea and vomiting, followed by headache and dizziness or vertigo, in order of frequency. 6. The most common neurologic signs on admission were impaired consciousness, constricted pupil with preserved light reflex and cerebellar signs. 7. The common site of cerebellar hemorrhage was right hemisphere, followed by vermis and left hemisphere, in order of frequency, and that of cerebellar infarction was right posterior hemisphere. 8. The better the consciousness on admission, the better the outcome of cerebellar stroke. 9. The following parameters indicated good prognosis with medical therapy, so called benign cerebellar hemorrhage: clear consciousness on admission, gradual onset type, less than 20cc of hematoma, no or mild hydrocephalus, no ventricular hematoma, no vermis involvement on CT scan.
