Clinical study was made by computed tomography (CT) in 32 cases of hypertensive intracerebral hemorrhage (HICH). The computed tomography was very effective in determining localization and extent of the intracerebral hemorrhage even to the ventricle. Hematoma was most frequently detected in the basal ganglion in 17 cases (54%) including 12 cases with the hemorrhage of the lateral type, which was confined to the putamen. The number of cases with the hemorrhage of the medial type, which was confined to the thalamus, was 6 and the number of cases with that of the mixed type was 5. Extension of hematoma to the ventricle was observed in 2 cases of the medial type and 4 cases of the mixed type. Four cases, showing the hematoma of the mixed type died in few days. Therefore it suggests that prognosis much more depends on an amount of the hemorrhage and the extent of cerebral damage rather than the presence of intraventricular hemorrhage. Hematoma was gradually absorbed at its marginal portion from 5 days after onset, and the ring zone of high density appeared from about 2 weeks after onset. This ring sign was observed in 50% of follow up cases. Hematoma perfectly subsided or remained as a small low density spot like cyst.
