Forty two patients were diagnosed as having subcortical(lobar) intracerebral hemorrhage among 407 consecutive patients presenting with spontaneous intracerebral hemorrhage. Brain CT and MRI or angiography were performed in 39 patients. The authors analyzed clinical features, brain CT, etiological factors, and outcome. Headache(69%) and vomiting(55%) were most common symptoms. The incidence of seizure was 14%. The volume of hematoma on CT was below 20cc in 21 patients, between 20cc and 40cc in 16 patients, and aove 40cc in 5 patients. The most common site of hemorrhage was parietal lobe in 32 of 42 patients. The mortality rate was 9.5% and the functional outcome of the patients was generally better than in other forms of intracerebral hemorrhage. Thirty one patients had arterial hypertension which was the leading cause. Two patients had AVMs and two patients had blood dyscrasias. Unknown etiology occurred in 7 patients. Neither brain MRI nor cerebral angiography showed abnormal vascular lesion in all of the pa tients who had arterial hypertension. We conclude that no further evaluation if recommended in patients with subcortical hemorrhage who were definitely diagnosed as having arterial hypertension.
