Twenty eight cases of the hypertensive intracerebral hemorrhage were examined with a CT scanner at 3-5 days before operation and one week after operation. The CT findings were studied from the point of postoperative functional recovery and mortality retrospectively.<BR>1) The cases of putaminal hemorrhage, which showed excellent recovery in motor function, showed a round or oval hematoma on CT, which did not extend to the internal copsule and surrounded by low density area laterally and anteroposteriorly.<BR>2) On the contrary, the cases of putaminal hemorrhage which showed poor recovery in motor function, showed larger hematoma, over 30 mm in diameter, on CT which extended to the posterior part of the internal capsule and was surrounded totally by low density area. Moreover, the case which showed irregular shape of hematoma, often resulted in poor recovery in motor function.<BR>3) In the cases of caudate hematoma, when the hematoma localized in the nucleus, recovery of motor function was excellent even by conservative treatment, moreover, even when the hematoma extended posteriorly or penetrated into the ventricle, mortality was also low.<BR>4) The cases of thalamic or subcortical hemorrhage were also discussed from the CT findings.
