Now a day, hypertension is more increasing in frequency and ranked the top of the causes of death in Korea and other nations. Most of cerebrovascular accidents in hypertensive patients are composed of vascular occlusive changes and hemorrhages. In cerebral angiogram, we can only detect occlusion of large artery and large mass effect from hematoma or cerebral infarction without identification of its entity. The computed tomogram, however, is the best way for evaluation of cerebrovascular diseases including detection of nature, location, amount and associated changes. This study includes evaluation of computed tomograms of 106 patients with hypertension during the period of 17 months from Feb. 1979 to June 1980 in the department of radiology, college of medicine, Hangyang University. The results were as follows . 1.Age distribution of the total 106 patients was board ranging form 25 years to 76 years. 67.9% of patients were over the age of 50. The male and female sex ratio was :2 . 2. 28 out of 106 patients were normal and 78 patients revealed abnormal on CT. findings ; those were intraacranial hemorrhage(35 patients), cerebral infarction(32 patients0 and brain atrophy(11 patients). 3. All of the intracrainial hemorrhage exceptone were intracerebral hemorrhage ; those were located in the cerebral hemisphere(19 patients), basal ganglia(15 patients) and brain stem(1 patient). The except one case of intracranial hemorrhage was subdural hematoma. 7 patients of intraventrivular hemorrhage and 1 patient of subarachnoid hemorrhage were combined with intracerebral hemorrhage.2/3 of patients who had hemorrhage in cerebral hemisphiere revealed lesions in the parietal and temporal lobes. 4. In cases of cerebral infarction, the cerebral hemisphere was most common site of lesion(20 cases0, and the next was basal ganglia(11 cases), Most of the in farcts in cerebral hemisphere were located in the parietal and temporal lobes. The left basal ganglia was more commonly invo ved than the right. After the contrast infusion, contrast enhancement was occured in 6 cases of cetebral infarcton. 5. In 11 patients with brain atrophy, 5 cases revealed cortical atrophy and the remainder was central strophy except one case of mixed lesion. 6. Degree of increased blood pressure was correlated with C.T findings ; in cases with severe hypertension, most of lesions on C.T. were intracranial hemorrhage. But in cases with borderline or mild hypertension. most of the findings on C.T were normal or cerebral infarction. 7. In case with hemiplegia or quardiplegia, most of the C.T findings were abnormal , especially intracranial hemorrhage. In patients with mild motor weakness or hemiparesis, most of the findings on C.T. were normal or cerebral infarction.
