[318 cases of intracerebral hemorrhage. A pathologic study (author's transl)].

The systemic analysis of cerebral hemorrhages (large single and multiple hematomas and small slit-hemorrhages) has been practiced in 318 patients. The emphasis is put on the site of the bleeding and the etiological data. Single hematomas were situated: 1) in 127 cases in the basal ganglia region (26 were medial, 44 intermediate, 48 lateral, 8 quadrilateral and one subthalamic), 2) in 67 cases in cerebral lobes (24: front; 22: temporal; 21 parietal) and 3) in 33 cases in the posterior fossa (19: cerebellum; 14: brain stem). Large hematomas in 71 cases and slit-hemorrhages in 20 others were multiple. In more than one case out of three, lateral hematomas extended into the temporal lobe and in one case out of two, the internal capsule was affected. The incidence of high blood pressure is significantly higher in patients with intermediate haematomas and slit hemorrhages. This factor is often found in lateral or cerebellar hematomas. Anticoagulant therapy is more frequent in lobar hematomas. In 43 cases without any proved etiology, the patients' mean age of death is inferior to that of the whole studied population. These findings are discussed in relation with the literature data.
