Nine patients with pure dysarthria underwent computed tomography or magnetic resonance imaging. Eight patients had infarcts of lacunar or larger size in the internal capsule: four in the superior portion of the anterior limb or adjacent corona radiata and four in the superior portion of the genu or the adjacent corona radiata. In one patient, there was a small infarct in the bulbar motor cortex. Dysarthria was transient and characterized by poor articulation in all cases. Five patients also had contralateral facial weakness, and three patients with lesions in the genu had minimal and transient involvement of the contralateral fingers. These three cases appeared to be variants of the dysarthria-clumsy hand syndrome. We submit that this syndrome should sometimes be regarded as a stroke syndrome rather than always as a lacunar syndrome.
9例单纯构音障碍患者接受了计算机断层扫描或磁共振成像检查。8例患者在内囊有腔隙性或更大面积的梗死灶：4例位于前肢上部或相邻的放射冠，4例位于膝部上部或相邻的放射冠。1例患者在延髓运动皮层有小梗死灶。所有病例的构音障碍均为短暂性，表现为发音不清。5例患者还伴有对侧面部无力，3例膝部有病变的患者对侧手指有轻微短暂受累。这3例病例似乎是构音障碍-笨拙手综合征的变异型。我们认为，这种综合征有时应被视为一种卒中综合征，而不应总是被视为腔隙性综合征。
