A Case Report of Three-Dimensional Fiber Tractography of Anterior Thalamic Radiation in a Capsular Genu Infarction

다국어 초록 (Multilingual Abstract)

Interruption of the anterior thalamic radiation (ATR) might explain cognitive impairment in an infarction of the genu of the internal capsule. However, a defect of the ATR in the genu infarction has received little attention. We report on a patient who developed cognitive impairment following the genu infarction. Diffusion tensor imaging revealed an interruption of the white matter fibers in the ATR. We suggested that cognitive impairments in the genu infarction were caused by a defect in the ATR.
