Abstract
- We investigated fifty four patients with spontaneous intracerebral lobar hemorrhage who were admitted to the Seoul National University Hospital Neurology Sercice during a period of five and a half years. Of these patients 25 (46.3%) had hypertension as the probable cause of hemorrhage Of the remaining cases, 12(22.2%) had other etiologies including 5 arteriovenous malforrnations. 3 aneurysms, 2 tumors, 1 Moyamoya disease and 1 superior sagittal sinus thrombosis, while 14(25.2%) had no apparent etiology. But some of them seemed to be due to cerebral amyloid angiopathy or occult vascular malformation. Parietal region was the most frequent site of hemorrage(23 cases, 42.6%). Six cases had multiple intracerebral hematoma. Common clinical manifestations were headache, vomiting, hemiparesis, seizure in order of frequency. Mortality rate was 16.7%, which was correlated with the size of hematoma (P<0.05) and consciousness level at the initial stage (p<0.05). But not with the presence of intraventricular or subarachnoid hemorrhage. Hypertension or age of onset.
