Cheiro-Oral Syndrome Due to Lesions in the Corona Radiata
Stroke 23:599-601, Omae,T.,et al, 1992
See this aricle in Pubmed

Article Abstract
We describe three patients with cheiro-oral syndrome caused by a small lesion in the corona radiata confirmed by high-resolution magnetic resonance imaging.Case 1:A 56-year-old hypertensive man who developed hypethesia and paresthesia in the left perioral area and hand was found to have a small hematoma just lateral to the right internal capsule.Case 2:A 67-year-old man noticed hypesthesia around the left mouth angle and thumb and index finger.Magnetic resonance imaging revealed a lesion in the right corona radiata.Case 3:A 45-year-old hypertensive man developed numbness in his perioral region and left hand that later spread to his shoulder. Magnetic resonance imaging revealed a recent small infarct in the lower lateral aspect of the right corona radiata.Conclusion:A small lesion in the corona radiata can cause cheiro-oral syndrome,whose pathogenetic mechanism in such patients may be explained by the somatotopical location or by the differing vulnerability of the neuropils in the corona radiata.
