Abstract

Foot drop usually results from lesions affecting the peripheral neural pathway related to dorsiflexor muscles, especially the peroneal nerve. Although a central nervous system lesion is suspected when there is a lack of clinical evidence for a lower motor neuron lesion, such cases are extremely rare. We describe a patient with sudden isolated foot drop caused by a small acute cortical infarction in the high convexity of the precentral gyrus. This report indicates that a cortical infarction may have to be considered as a potential cause of foot drop.
