Leukoaraiosis and intracerebral hematoma.

We studied 33 consecutive patients with computed tomographic findings of decreased density in the periventricular white matter (leukoaraiosis). Computed tomograms in five (aged 56-75 years) of the 33 demonstrated intracerebral hematoma. The hemorrhages were situated in the thalamic area in four and in the parietotemporal area in one patient. These five patients were hypertensive and had signs characteristic of parenchymal hemorrhage. Three of the five patients had progressive dementia prior to the ictus, and two of the three also had a history of single or multiple strokes. There was no significant difference in the clinical findings of hematoma patients with or without leukoaraiosis.
