Thalamic hemorrhage: Clinical-CT correlations

We studied 50 patients with thalamic hemorrhage, 84% with hypertension. Five patients had hematomas less than 8 mm and signs that resolved within 4 days. Two patients had headache, papilledema, and hemorrhage contiguous with the lateral ventricles. Twenty-four had hemiparesis, parenchymal hemorrhage 9 to 30 mm, and no ventricular blood. Nineteen had a larger hemorrhage and intraventricular hemorrhage, impaired consciousness, hemiparesis, and pupillary abnormalities; 12 had vertical gaze impairment, and all 19 patients died.
