Clinical observations of 424 patients with intracerebral hemorrhages (314 with parenchymatous-ventricular and 110 with parenchymatous) verified at autopsy are reviewed. An analysis of the observations allowed the differentiation of the very acute, acute and subacute forms of parenchymatous-ventricular hemorrhages. The incidence of some "classical" symptoms of parenchymatous-ventricular bleeding was shown to change. The erroneous diagnosis of the ischemic nature of the stroke in 7.7% of observations was analyzed. The accuracy of computing differential diagnosis (using Bies's procedure in postulating the independence of the signs) was 75-79% depending on the type and localization of cerebral hemorrhages.
