• A 60-year-old patient developed leg weakness leading to spasticity, secondary to a sharply localized infarction of the medullary pyramids. Within a month, spasticity had replaced the initial flaccidity. Several years later, rupture of an atherosclerotic aneurysm of the basilar artery led to subarachnoid hemorrhage and eventual death.
