Thalamic hemorrhage. A prospective study of 100 patients.

Background And Purpose: The clinical features of thalamic hemorrhage in terms of localization are of great interest in many studies. To better understand the relationship between the localization of thalamic hemorrhage and clinical features. we evaluated the characteristics of patients with four different topographic types of thalamic hemorrhage.

[Callosal infarction after bilateral occlusion of the internal carotid arteries with hemineglect syndrome and astasia-abasia].

We report a patient who had a callosal infarct, showed by Computer Tomography and Magnetic Resonance Imaging, without injury to the adjacent hemispheres. Angiography revealed an occlusion of both internal carotid arteries. Besides interhemispheric disconnection with unilateral left agraphia, left tactile anomia, left ideomotor apraxia and left ear auditivoverbal extinction, the patient showed signs of left hemineglect and astasia-abasia, both persistent.
