A 39-year-old man was admitted to our hospital because of atrophy of the right side of the tongue of 6 years' duration. Neurological examination showed atrophy and fasciculations in the right side of the tongue. Magnetic resonance imaging showed atrophy and high signal intensity areas on T1 and T2 weighted images in the right masseter, temporal, lateral and medial pterygoid muscles. Electromyography showed fibrillations and positive sharp waves at rest, high amplitude polyphasic motor unit potentials with weak contraction in the right tongue and masseter muscles. Examination of autonomic functions suggested postganglionic lesion of right facial sympathetic nerves. We believe that this case may be related to progressive facial hemiatrophy.
一名39岁男性因右侧舌萎缩6年入院。神经系统检查显示右侧舌萎缩并伴有肌束震颤。磁共振成像显示右侧咬肌、颞肌、翼外肌和翼内肌在T1加权像和T2加权像上有萎缩及高信号区。肌电图显示右侧舌肌和咬肌在静息时出现纤颤电位和正锐波，轻度收缩时运动单位电位波幅增高且多相。自主神经功能检查提示右侧面部交感神经节后病变。我们认为该病例可能与进行性面部半侧萎缩有关。
