There have been sporadic case reports of a restricted sensory syndrome caused by stroke, most often as a cheiro-oral syndrome. We describe 14 patients with stroke who showed various restricted sensory syndromes and correlated their symptoms with the radiological findings. Twelve had small infarcts and two had haemorrhages; six had lesions in the posterolateral thalamus, five in the pontine tegmentum, one in the lenticulocapsular area, one in the frontoparietal subcortex, and one in the frontal white matter. Sensory abnormalities were in the perioral area, hands, fingers, feet and toes, in various combinations. Two patients with pontine stroke had bilateral sensory abnormalities associated with paramedian lesions. Thus, strokes in the sensory pathways can cause various restricted sensory syndromes of which 'cheiro-oral syndrome' is only one variant. Magnetic resonance imaging is of interest in the clinicoradiological correlation, and helps elucidate the somatotopic pattern of the human sensory pathways.
已有关于中风导致局限性感觉综合征的散发病例报告，最常见的是口手综合征。我们描述了14例表现出各种局限性感觉综合征的中风患者，并将他们的症状与放射学检查结果进行了关联。其中12例为小梗死灶，2例为出血；6例病变位于丘脑后外侧，5例位于脑桥被盖部，1例位于豆状核囊区，1例位于额顶叶皮质下，1例位于额叶白质。感觉异常出现在口周区域、手部、手指、足部和脚趾，表现为各种不同的组合形式。2例脑桥中风患者出现与旁正中病变相关的双侧感觉异常。因此，感觉通路的中风可导致各种局限性感觉综合征，其中“口手综合征”只是其中一种变体。磁共振成像在临床与放射学关联方面很有价值，有助于阐明人类感觉通路的躯体定位模式。
