title: [Hemiballism as a result of a focal hemorrhagic lesion of the subthalamic nucleus documented by CT].
abstract: The authors relate a case of hemiballism with favourable evolution, suddenly arisen in an hypertensive subject, in whom the CT (Computer Tomography) pointed out a small hemorrhage at the level of the subthalamic nucleus (body of Luys), controlateral to hypercinesias. The authors underline the extreme rareness of such clinico-radiologic association since more than 10 years after the introduction of CT only another analogous observation has been related in literature. Cases of hemichorea and/or hemiballism, secondary to ischemic, hemorrhagic or angiomatous lesions, variously situated at the level of basal nuclei have been more often documented through CT.
