Abstract
It has been established that cerebral ptosis may follow unilateral, usually right, hemispheric lesions, suggesting the lateralization of supranuclear control of the levator palpebrae superioris. However, the exact anatomical location and paths responsible are not yet known. Moreover, the reason why patients with cerebral ptosis may follow a grave course is not understood. Here, we report two cases of cerebral ptosis, that developed at the time of impending herniation. The temporal relationship and reiteration of the ptosis and brain herniation support the assumption that the mechanical compression of descending paths from the right hemisphere to the brainstem evokes cerebral ptosis. Therefore, we think cerebral ptosis may be an early sign of impending herniation in large hemispheric infarcts.
