Ninety-two percent of 100 patients with putaminal hemorrhage were hypertensive.Of the eight normotensive patients,seven were substance abusers or had bilateral putaminal hemorrhages.The one other normotensive patient was less than 40 years old.The 100 hemorrhages had the following locations:1.medial putaminal(17 cases:six were normotensive and less than 40 years old and five were substance abusers);2.lateral putaminal extending through the external capsule(eleven cases);3.putaminal-capsular and subcortical shite matter(32 cases);4.putaminal cerebral hemispheric(19 cases);5.putaminal-thalamic(19 cases);6.bilateral(two cases).A disproportionate number of black patients suffered hematoma extension to the cerebral hemispheres or thalamus(46%)compared to Caucasians(23%). Overall mortality was 20%(17 blacks and three Caucasians)and occurred in patients with hematoma extension to the thalamus or cerebral hemispheres. Contrast-enhanced CT was performed in all 100 patients and provided no additional diagnostic yield.This indicates limited use for enhanced CT in hypertensive patients with putaminal hemorrhage who have a characteristic appearance of the acute hemorrhage on the nonenhanced CT. |
