Five right-handed patients suffering from a recent CT-assessed left posterior thalamic hemorrhage are reported. In all patients a standard language examination performed within one month after stroke onset did not reveal aphasic disturbances. While the present series argues for the role of intrathalamic lesion localization, a review of the literature suggests that lesion site per se does not always account for the presence or absence of aphasia in the individual case. The importance of reduced blood flow and metabolism in cortical areas which appear undamaged on CT scan is briefly discussed.
报告了5例近期经CT评估为左侧丘脑后部出血的右利手患者。所有患者在卒中发作后1个月内进行的标准语言检查均未发现失语障碍。虽然本系列病例支持丘脑内病变定位的作用，但文献综述表明，病变部位本身并不总是能解释个别病例中失语症的存在与否。本文简要讨论了CT扫描显示未受损的皮质区域血流和代谢减少的重要性。
