Neurological picture. Isolated toe paralysis caused by a small cortical infarction.

摘要

CASE REPORT:A 66-year-old man developed acutely distal weakness of the left leg. Neurological examination 8 h after the onset revealed isolated weakness of the left foot and toes. Ankle dorsiflexion and eversion were more affected than inversion and plantar flexion. After 48 h from the onset of symptoms, the patient had completely recovered from ankle weakness whereas paralysis of toe dorsiflexion and severe paresis of toe plantar flexion persisted. Tapping movements with the left foot were slower than on the right and recruited synkinetic movements of the ipsilateral knee and hip joints. Tapping with the left foot induced involuntary contralateral "mirror" movements but no such movements occurred on the left during intended unilateral movements of the right foot.
