Dysarthria is the principal motor abnormality following vascular damage to pontine paramedian structures, owing to the involvement of corticobulbar fibres. Here we describe 2 cases of adults affected by dysarthria following transient muteness as the result of a stroke in pontomesencephalic structures. Their clinical outcome was very similar to that of young patients who have undergone surgery of the 4th ventricle. Recently the importance of pons involvement has also been underlined in these cases. This case report suggests the existence of a functional network for speech, in which the pontomesencephalon is an important station for the triggering and the efficacy of verbal production.
构音障碍是脑桥旁正中结构血管损伤后的主要运动异常，这是由于皮质延髓纤维受累所致。在此，我们描述2例成年人，他们在脑桥中脑结构中风后出现短暂性缄默，随后出现构音障碍。他们的临床结局与接受第四脑室手术的年轻患者非常相似。最近，在这些病例中脑桥受累的重要性也得到了强调。本病例报告提示存在一个言语功能网络，其中脑桥中脑是言语产生触发和功效的重要站点。
