We report a patient who manifested cheiro-oral syndrome following a cortical brain infarction without involvement of postcentral gyrus. A 67-year-old man was admitted to our hospital because of sudden paresthesia in his right face and right thumb and index finger. His cranial magnetic resonance imaging disclosed that the infarction was located in the left precentral sulcus and at the base of the central sulcus, while the left postcentral gyrus was not involved. His sensory symptom was attributed to the lesion of the Brodmann's area 3a, which is located at the base of the central sulcus. We postulate that the lesions responsible for cortical cheiro-oral syndrome are dispersed more widely than those for thalamic or pontine ones, since the somatotopy of face and hand in the cortex is distributed more extensively than that in the thalamus or pons.
我们报告了一例在皮质脑梗死且中央后回未受累后出现口手综合征的患者。一名67岁男性因右脸、右手拇指和食指突然出现感觉异常入院。他的头颅磁共振成像显示梗死位于左侧中央前沟及中央沟底部，而左侧中央后回未受累。他的感觉症状归因于位于中央沟底部的布罗德曼3a区的病变。我们推测，导致皮质口手综合征的病变比丘脑或脑桥病变的分布更广泛，因为皮质中面部和手部的躯体定位分布比丘脑或脑桥更广泛。
