Ipsilateral hemiparesis and contralateral lower limb paresis caused by anterior cerebral artery territory infarct

Ipsilateral hemiparesis is rare after a supratentorial stroke, and the role of reorganization in the motor areas of unaffected hemisphere is important for the rehabilitation of the stroke patients. In this study, we present a patient who had a subclinical remote infarct in the right pons developed ipsilateral hemiparesis and contralateral lower limb paresis caused by a new infarct in the left anterior cerebral artery territory. Our case suggests that the motor areas of the unaffected hemisphere might be reorganized after stroke, which is important for the rehabilitation of stroke patients.
