The telodiencephalic ischemic syndrome.

A new cerebral syndrome is described which occurs rather frequently with ischemia affecting the common pathway of the internal carotid and middle cerebral arteries. The syndrome consists of contralateral brachiofacial hemiparesis, possibly with hemianopia and/or aphasia, and ipsilateral thermoregulatory hemihypohidrosis with an ipsilateral central Horner syndrome. It is caused by an ischemic lesion of the crossed pathways descending from the cerebrum and the uncrossed hypothalamo-spinal sympathetic pathways descending through the subthalamic region. It is suggested to name the syndrome "telodiencephalic ischemic syndrome".
