A 57-year-old right-handed man was admitted to our hospital because of right facial paresis and acute-onset dysarthria. He presented with non-fluent aphasia. His aphasia gradually improved, but he started speaking with a strange accent and intonation from the fifth hospital day. He was diagnosed with foreign accent syndrome (FAS), which lasted for 2 months. MRI revealed ischemic infarction with edema in the superior, middle, and inferior parts of the left precentral gyrus. One year later, MRI revealed old, small infarct lesions in the left precentral gyrus, middle frontal gyrus, and postcentral gyrus. We suspected that FAS developed because of disturbance of prosody in the speaking network on improving his aphasia. His meticulous character was probably influenced on developing FAS. The responsible lesions possibly were those in the reversible parts of the left precentral gyrus with edema on acute stage.
一名57岁的右利手男性因右侧面部麻痹和急性起病的构音障碍入住我院。他表现为非流畅性失语。其失语症状逐渐改善，但从住院第5天起，他开始说话带有奇怪的口音和语调。他被诊断为外国口音综合征（FAS），持续了2个月。MRI显示左侧中央前回上、中、下部有缺血性梗死并伴有水肿。1年后，MRI显示左侧中央前回、额中回和中央后回有陈旧性小梗死灶。我们怀疑FAS是由于失语改善过程中言语网络韵律紊乱所致。他一丝不苟的性格可能对FAS的发生有影响。责任病灶可能是急性期左侧中央前回有水肿的可逆部位的那些病灶。
