To the Editor.  —In a recent article, Ichikawa et al (Archives 1982;39:585-586) discussed the possible causes of ataxic hemiparesis. We report a case of ataxic hemiparesis with an ischemic lesion in the basis pontis, clearly shown by computed tomography (CT).

Report of a Case.  —A 72-year-old man experienced weakness of the right arm and right leg on awakening and noticed some numbness of the right hand. On admission to the hospital two days later, his BP was slightly elevated (160/100 mm Hg). Physical and cardiac examination results were not remarkable. There was right-sided hemiparesis; strength was reduced to four fifths in the extensor muscles of the upper extremity and to three fifths in those of the lower extremity. There was a right plantar reflex to the extensor muscle, as well as mild ataxia in the right arm and severe ataxia in the right leg. The patient could not stand up
