The authors analyzed 619 patients with spontaneous intracranial hemorrhage which had been diagnosed by brain CT scan. The following results were obtained; 1) The causes, in descending order of frequency, were aneurysm, hypertension, arteriovenous malformation, tumor, Moyamoya disease, blood dyscrasia and infarction. 2) The peak incidence age was in the 5th and 6th decades, but arteriovenous malformation cases showed peak incidence in the 3rd decade. 3) The peak incidence season was spring, but arteriovenous malformation cases showed even distribution around the year. 4) Of the 619 cases, 445 cases(71.9%) were treated operatively. Of them, 321 cases(51.9%) were treated radically, removing the cause of hemorrhage. 5) Regarding the frequent site of hemorrhage, SAH was present in 94% of aneurysm cases, ICH in 99% of hypertension cases and 85% of arteriovenous malformation cases, and SDH in 80% of blood dyscrasia cases. 6) Aneurysm cases showed best prognosis and hypertension cases showed most serious prognosis. 7) Cases with intraventricular hemorrhage showed poor prognosis.
