Computerized tomography in intracranial hemorrhage.
Three hundred patients with intracranial hemorrhage were studied by computerized tomography (CT). Thalamic-ganglionic hematoma was found in 232; the mortality increased from 25% to 70% if ventricular extension occurred in this group. Lobar hematoma occurred in 45 of these patients, with a mortality of 20%, which was not influenced by ventricular extension. Seven had intraventricular bleeding only; of these, two died. In 12 patients with CT evidence of cisternal blood, angiography demonstrated aneurysms; the location of the blood predicted the location of the aneurysm in six. Multiple spontaneous intracerebral hematomas (ICHs) were visualized by CT in five patients. In 29 of 146 cases of ICH, postcontrast study showed enhancement; in 15, this was consistent with neoplasm, angioma, or aneurysm. In 14 with spontaneous ICH, ring enhancement occurred ten days to six weeks following hemorrhage.
