Severe episodes were sometimes associated with transient right eye mydriasis (Figure 1), significant lower extremity weakness and at times confusion that all resolved with the resolution of her migraine episode. Physical examination revealed a fixed dilated right pupil (Figure 1), decreased proximal and distal muscular strength (3/5) in the lower extremities with normal reflexes.
