Isolated facio-lingual hypoesthesia and weakness is rare. We describe a case of isolated facio-lingual hypoesthesia and weakness after a hemorrhagic infarct localized at the contralateral operculum. A 66-year-old woman developed acute onset of facio-lingual hypoalgesia, hypoesthesia, and weakness, with no such symptoms being observed in other parts of the body. Brain magnetic resonance imaging showed a subacute hemorrhagic infarct in the right frontal operculum, which spread slightly to the right temporo-parietal operculum. (123)IMP-SPECT showed hypoperfusion in the right fronto-temporo-parietal operculum, as detected by MRI, without apparent diaschisis within the brain. Neuroimaging findings for our patient suggested the involvement of the primary somatosensory-motor cortices (S1 and M1) and the secondary somatosensory cortex (S2), which receive trigemino-thalamo-cortical pathways.
孤立性面舌感觉减退和无力较为罕见。我们描述了一例在对侧岛盖部发生出血性梗死之后出现孤立性面舌感觉减退和无力的病例。一名66岁女性急性起病，出现面舌痛觉减退、感觉减退和无力，身体其他部位未观察到此类症状。脑磁共振成像显示右侧额岛盖部有亚急性出血性梗死，病变轻度蔓延至右侧颞顶岛盖部。单光子发射计算机断层扫描（IMP-SPECT）显示，如磁共振成像所检测，右侧额颞顶岛盖部灌注减低，脑内无明显远隔功能障碍。我们患者的神经影像学检查结果提示，接受三叉丘脑皮质通路的初级躯体感觉运动皮质（S1和M1）以及次级躯体感觉皮质（S2）受累。
