Abstract
One hundred and twelve patients with spontaneous supratentorial intracerebral hemorrhages were reviewed to identify features which distinguish lobar intracerebral hemorrhage (LH; n=42) from thalamic or basal ganglionic hemorrhage (TGH; n=70). Chronic hypertension occurred more commonly in TGH (TGH 67%; LH 48%) while bleeding diathesis was more common in LH (LH 19%; TGH 6%). Clinical presentations were extremely variable and not associated with the type of hemorrhage. Bleeding into the ventricles and hydrocephalus occurred more often with TGH. At last follow-up, there were minimal differences between LH and TGH in overall mortality and functional outcome of the survivors. Alertness on admission was associated with a good outcome regardless of the type of hemorrhage, while a low Glasgow Coma Scale score, coma, ataxic respiration, abnormal pupil reactions, acute hypertension, large hemorrhage size and intraventricular blood were associated with a poor outcome. These data confirm etiological distinctions between LH and TGH, but fail to confirm previously reported differences in clinical presentation and outcome.
