ABSTRACT
The authors analyzed 34 cases of spontaneous cerebellar hemorrhage which was diagnosed by brain CT scan, and assessed the relationship of outcome to the volume of hematoma, location of hematoma, level of consciousness and the CT apperance of the quadrigeminal cistern. The results were summerized as followed : 1) Hydrocephalic changes were observed in 25 patients(73.5%) and were identidied in 21 patients of the 22 patients with intraventricular extension of gemorrhage. 2) The volume of cerebellar hematoma sigificantly correlated to the level of consciousness on admission and prognosis. Patients with large hematoma showed poor prognosis. 3) Obliteration of quadrigeminal cistern on brain CT scan significantly correlated to the level of consciousness and prognosis. The patient with complete obliteration of quadrigeminal cistern on CT scan revealed unfavorable outcome. 4) The level of consciousness was the most important prognostic factor and the decreased level of consciousness was the indicator of poor result. 5) The location of hematoma did not correlated to the prognosis.
